This problem has been around for ever. When browsing roblox.com using an iOS Device (and Android?) and listening to music, the website will pause whatever you have playing for no reason. It’s really annoying and I’m not sure if this is bug is a feature.
tl;dr: Safari stops other sounds from playing if it thinks the page contains media that makes noise. [/quote]
I do believe this is the case. If you have sound playing, and you nagivate away from the source of the sound to a new app/source of sound, it assumes you are no longer interested in that media, and stops the currently playing sound to be replaced by your new interest. It’s somewhat annoying, but prevents those random moments when your listening to music, then this random ad/etc starts playing out of no where.
I do not seem to be having this issue while using the Chrome app for iOS. A ‘disadvantage’ is that it will not mute your music even if you’re watching a fullscreen movie.
