When it works, things are good. I can switch modes relatively easily. Since a recent update, things have become a bit flaky. My phone consistently loses connection to one of the hearing aids. Restarting the phone usually fixes it, but doing this every time I need to change modes is beyond frustrating. **UPDATE I was contacted by support at ReSound. They say the problem is due to an issue with Andriod 12, and they are working on a solution. I hope the solution comes very soon.
