Looking online and searching the Brave Community for info, there is no precise solution for Brave Browser (iOS) users, that works for all websites.
In January 2025, I had thought the following should work:
Brave Browser Settings > FEATURES > Playlist >
Disable everything . . . test . . . and later, enable what you will.
You might also do an iOS Shutdown.
But such Brave Browser (IOS) Playlist controls and steps apparently do not work for all websites.
If you have a list of websites where that is the case, you might list the websites here, and perhaps Brave Support member @Mattches will pass that info along to Brave developers.
