Doorbell not connected error

[jsaus63304]

Recently, doorbell camera stopped working.   After 3-4 frustrating days of uninstalling/installing, resetting, troubleshooting to no avail... it just started working again.

Now, every time I turn on the app, it says "Doorbell not connected to smart hub,,,,,,,,"  In a few seconds, it connects and seems to work fine.  All other cameras on hub work normally with no error messages.

What gives?   Did not do this previously.

Could be a signal strength and/or quality issue. Are there any other wireless devices that use the 2.4GHz band near the doorbell? What is the signal strength shown in the app or web client for the doorbell?

The signal strength is grayed out.
