iOS 16 and a voiceover problem

I am a voiceover user, and I’m wondering if anyone else has experienced the problem I’ve been having since updating to iOS 16. Frequently, the app switcher will quit working. It doesn’t matter what I’m doing, no specific tasks, but the app switcher will no longer be available. I will have to turn off my phone and then turn it back on, and then the app switcher will once again work. This happens at random times, sometimes right away in the morning, other times later in the day. I have the app switcher set up on back tap, and even that won’t work. Like I said, the only way to make it work again, is to turn my phone off and turn it back on. I updated today to the latest update, hoping the bug fixes would correct this, but sadly it did not. Does anyone know if there is a bug fix coming soon to correct this problem? It’s really annoying. Thanks.
