No longer getting "tune" sound with door opening

Still waiting. I no longer get any sounds when my doors open.

I had no sensors making a sound anymore. Went though chat, sent logs and heard nothing from anyone at Wyze. Contacting them a second time. Did resets, turned tune on and off-back on again, set to high, etc and nothing fixed it. Was told to send logs again and of course i resisted since the first time nobody got back to me. Hub out of warranty so I wanted to purchase a new hub to see if that worked. Was told couldn’t purchase a hub by itself, only WITH monitoring service which we are already subscribe to. As you can imagine I told chat support this was the dumbing thing I ever heard and pressed that it’s a safety issue not having ANY sound coming from the hub during an alarm or doors opening. Support then decided they would send me a new hub without paying for it out of a courtesy. I can confirm, I got the hub today and after adding it to the app, deleting the old hub and going through setting up the monitoring in the app (Yes, it kept the same service which was a big deal for us since we are paying the introductory rate before the price increased), miraculously, the hub now makes a sound when a door is opened again. I haven’t tested the alarm yet, but I can’t imagine that won’t work. The firmware is up to date. Not sure what caused it to stop making sound but I can 100% confirm by replacing the hub, fixed it. Has anyone tried deleting the hub from the app, add adding it again to see if that fixes the sound issue? Is it a HW issue or some bug in the software???
