If you have a high sub badge (as in you've been subbed to a particular streamer for a long time), but you liked the look of a previous sub badge better, it would be really nice to view earlier sub badges, especially if a streamer is offline who doesn't have a very active offline chat. I was thinking earlier that it might be nice to actually change your badge to an earlier one that you might think is prettier, but that might be too confusing and it would probably not be a good idea to deceive the streamer who probably doesn't always have time to actually hover over the badge and see how long the user has actually been subbed for LUL.

Have a way to make a set of collections (not every collections playlist) subscription locked. There is a way to make a whole channel subscriber only viewing. Why not have it to where a broadcaster can lock a set of videos for those who chose to support the streamer financially while not taking away from those who can't or choose not to subscribe? In this concept, being able to keep past broadcasts and other uploaded content not in that collection completely open to everyone.
Idea behind it: I like to edit streams and other content into condensed highlights and upload them to Twitch and YouTube, my concept in doing this, is to remove the third step of redirecting subs to another place such as Patreon or Discord for access to videos early. Having a place on Twitch would be much easier to allow subscribers early previewing/first looks on content before it becomes public to everyone. This way it would give another perk to subscribing if this is something the broadcaster does, without forcing the viewer to be apart of another process.
But it's not just limited to the idea of early content viewing, this would also add another option of having permanent subscriber only content in the same way there is sub only streaming.

Provide custom servers for channel subscribers/twitch prime - this would allow streamers to play with their communities without the hassle of renting a server, plus you could charge more for prime if it was included to be able to join a custom server of the person you use your prime sub with. It would stop stream snipers as the streamer would have total control over the server, plus as it would be provided by Amazon, they would be able to use all the latest security to avoid it being DDOSS'd and hacked.

I feel this is really needed for certain games that are prone to being DDOSS'd on custom servers like Battlefield 4, and most likely a lot of other games.

When checking subscription information on the Twitch mobile app there is a discrepancy in the language used which can lead to confusion and unintentional and unwanted payments.

When viewing the summary of all current subscriptions, subs set to renew do include a line which states that they will be renewing and the date of renewal, however — in the expanded info on a subscription, regardless of whether a subscription is set to renew or will be ending, it says that the subscription will be expiring on that date. While user caution is important, this discrepancy can (and has, in my case, as when I view my subscription info I go directly to the page with the most info) lead to unintentional and unwanted renewal of subscriptions.

My suggestion is to change the expanded information language to match the summary information language for a cohesive message that prevents any confusion.

this is what happened, there was a channel that i liked and did got a subscription for 6 months(for the promotional price), so this streamer did not got online for a month, and i did forgot about the subscription, this week i got a message in my cred card app about a charge that i did not remembered. some research and was a 6 month subscription.
so my suggestion is i if there an option in the subscription manager page that would send an email, 5, 3 or 1 day before my subscription automatically redeemed.
for short an option to receive an email if one subscription is close to renew itself in the subscription manager page.

I get very tired of the Apple TV app telling me that my free preview has ended for channels I’ve paid to sub.
Happens most times when we go into the app, then into the channel, after having watched the channel the previous night.
If you exit the stream, open another one, and then go back, the error is gone.
At least change the wording on the error... my goodness, I’ve subbed them for 11 months. It’s not my free anything, lol, at that point.
It’d be really cool if it said, hey the session has expired please refresh, because the first time it happened I was mad and confused until I figured out how to “refresh it.”
I’m sure this is an odd situation because we watch one specific stream pretty much every night. It doesn’t happen when switching streams (watching different ones I guess?), and does not happen on the iOS App or Desktop as far as I know. Only on the Apple TV. It’s the 4th gen but without the 4K. Happens on multiple Apple TVs (same model both WiFi) but on the same account of course.
I really don’t care that the error occurs it’s easy to fix. Please please change the wording so it says how to fix it.
Again you gotta open a different stream (or at least it’s live preview) and then go back.
Thanks
