I have submitted a feedback email through the browser itself, but this looked like a better place to get traction.
On iOS, with Brave installed, the phone does not consider it an “official” browser at all. If Chrome is installed, iOS recognizes it as a proper browser (see photo). In my case, this prevents me from being able to use a Cydia app to select it as my default browser, however I’m sure it has ramifications for other apps as well. Hopefully it’s something simple, because iOS is obviously expecting something it isn’t seeing. Thanks!
