Starts flashing green

Shelly motion sometimes stops working. When motion is detected, it flashes green, but the light (through the action) does not start, nothing is logged. In the application, the sensor reports as "Non active".

What is causing this and how to deal with it?

Any suggestion?

The setting is original. In my weekly schedule, I was set to turn off at midnight and turn on at 6 in the morning. The wifi turns off at midnight and also turns on at 6 in the morning, so it is possible that before the wifi turned on, it did not have time to turn on the sensor and later this setting is no longer applied. Possible?
