Ring Pro Goes Offline Every Night!

I have a new Ring Pro Doorbell, a new Ring transformer, and a new Ring Pro Chime. Every night around 11:45pm or after my Ring Pro Doorbell goes offline !!! Every night !!! I press the reconnect from my phone and nothing happens. I check the doorbell status around 3:00am or 4:00am and its back online. It's offline for 3 to 4 hours every night!!! It stays online all day. All of my other devices: Ring Floodlight, the Echo and the Chime works fine and remain online. They never get offline. Just the Ring Doorbell Pro. I have called support and they just suggest the same thing, reset my router when it's clearly not the router if all of the other devices I mention are woking and never get offline. I see from reading in the Ring community and Amazon reviews that there is a major problem with the Ring Doorbell Pro going offline often. Rebooting my router is not the solution. Any suggestions for fixing my Ring Doorbell Pro that goes offline every night for 3 to 4 hours?
