iOS is way worse when it comes to support for things like this. IOS started super restrictive and slowly allowed for slightly more background app support, but anything off the beaten path of “open app, view stuff, leave app” is not well supported on iOS.
Android would historically allow apps to do whatever the fuck they wanted, but in the past like 6 years started adding restrictions, and then started adding some mechanisms for users to allow exceptions.
It’s very unsurprising for Android to support these cases better, but they’re honestly both getting worse, because “battery optimization”, and it really hurts “off the beaten path” applications.
