iOS WyzeBeta app v2.28.2 (a24) has resurrected a freezing bug. Once again, it froze my iPhone so badly that the clock stopped running and the phone was totally non-responsive to ANY button or combination of buttons. After 5 minutes, the iPhone rebooted by itself—fortunately, because there was no way to power it off or force it to reboot.
This was an ongoing problem in a prior version of the iOS app; no other app has ever done that to my phone. It’s disastrously bad coding.
