@Ramfat73 If can only answer one or the other, I guess I’d say it’s a Rumble issue. This is more theory than anything because I lack the expertise and haven’t spent a lot of time, but just from my basic observation and testing on a few browsers, the issue appears to be based on how Rumble has everything coded. It’s kind of the interplay between them trying to show ads and all, which gets stopped if you’re blocking autoplay. Basically it’s trying to open and autoplay something but your settings is preventing it. And they aren’t loading it as content you can then try to pause/play.
That said, I guess will try to tag in @Mattches to see if he has a more accurate or thorough explanation. Also not sure if is something they might think should be looked at for web compatibility or anything.
