Experienced the same exact issue on the original Chimes. Used Android app 3.22.2 as well as reverted back to 3.20.0 with no luck. I have two chimes and both exhibit this issue. Tried resetting the chime as well as removing / re-adding device.
It seems like no updates are being pushed out upon click of update.
I was able to update the tone chime two months ago.
With so many posts exihibiting this issues, it’s most likely related to wither a firmware or backend issue.
