Great to hear it is working now.
With it coming and going like this, if I had to guess the likely culprit i’d guess it was wireless interference (just a guess). If it happens again, try the other side of the house/change potential interference.
The reality of complex electronics with its underlying hardware-firmware-OS-RAM filled with ever changing data-radios frequent Tx/Rx, a device can get into an odd state. Sometimes a reboot resolves it but occasionally it does get resolved by the ghost in the machine.
If you believe the issue is resolved, it’s up to you if you’d like to mark it solved.
