Wyze Lock Bolt no sound / beep

Has anyone experienced this yet? My Wyze Lock Bolt keypad doesn’t make a sound any more. Also, when I add fingerprints, there’s no beep, or even when I have too many failed attempts to open the lock.

I’m thinking the speaker is faulty in my lock unit.

Or is this a firmware bug … I don’t think so as I’ve updated the last few firmwares and the issue hasn’t been fixed.

If nobody else has experenced this, I’m tempted to just warentee a new lock, but I don’t want the hassle of entering all the fingerprints again…
