On iOS, it is not recommended to use multiple crash reporters in the same app, as this may lead to unknown behavior. iOS doesn’t support having multiple crash reporters per app due to the way exception and signal handlers work. It is not guaranteed that all crash reporters will catch all exceptions and signals, so your crash reporter(s) could miss quite a few crashes.
On Android, multiple crash reporters can be used simultaneously; however, please make sure Instabug is initialized after all other crash reporters.
