Is working OK in iPhone SE (2020) with the latest Beta (15.3). I haven't experienced any problems with the Beta releases, you might enroll in the Beta program and see if the latest vers. helps.
Other than the somewhere, daily updates, it seems to keep doing, so far, after every update, I have to "stop" the application in the apps menu to clear out the old libraries from RAM, then when I run it again, everything works as it should.
