Ring Doorbell Pro 3 keeps going offline in the afternoons

I have a Ring DoorBell Pro 3 installed at my home and in the last few days, whenever the external temperature goes warmer (18 degrees celcius or above), the device goes offline but comes back on its own later in the evening or night when it is cooler. The device is plugged in to a transformer and there seems to be no issues with power supply and my home WIFI is fine. The other 3 Ring devices connected to the WIFI are working fine. It seems to go offline around 2pm in the afternnon and then comes back on its own around 10pm.
