Prorate subscription price based on subscription time not used when purchasing a subscription upgrade
If I sub to a user with a 6 month 4.99 sub and then during my third month decide that I want to upgrade my sub to 9.99 I think Twitch should charge me the difference of time remaining and then once my sub renews at the end of the initial 6 months, it would charge me for my plan at the new price.
In the case above, I have 3 months left unused in my sub. So for today, to upgrade my sub, I pay $15 to be brought up to the 9.99 tier for the next three months. Twitch and the streamer can split the difference depending on their arrangement. Then when that sub ends, I'd be charged the full price of a 6-month 9.99 sub when I renew.
As it is now, if I buy a bulk sub, I'm locked in at that level unless I want to lose my investment in that sub to upgrade. So, for anyone buying a 6 month sub, you are actually disincentivized to upgrade your sub.
We are working on some more robust multi-month tech and robust upgrade/downgrade tech. So when we get both done we’ll definitely incorporate this functionality.
Any updates on this? I'd love to be able to do this for streamers I enjoy a ton!
