If a channel raids another channel the raiders shouldn't be greeted by an ad
When a channel raids another channel the raiding viewers shouldn't be greeted by an ad immediately. It disrupts the fun flow of things for the raiding viewers, and can disrupt the flow of users sending raid messages as a collective whole. It also entices raiding viewers to abort the raid on their end by closing their browser to avoid the ad. It's damaging more than helpful.
Good news! We have actually released this and you should not be seeing ads when you are a participant of a raid. If you are please reach out to our support team at help.twitch.tv otherwise please refer to this article that talks about the changes a little bit more https://help.twitch.tv/s/article/ads-experience-updates?language=en_US
true it makes the transition hard for the viewers. but 15 minutes later if they stick around they should get ads or an additional ad
