Google Pixel 4 XL on cellular and live view no longer working

I have 2 Google Pixel 4 XL and live view no longer works on the Ring app on all my cameras and doorbell. I get error ‘Failed to connect’.
I was told to try the Rapid Ring app and it works fine while connected to both cellular or WiFi

When my 2 Google Pixel 4 XL smartphones are on WIFi, I am able to live view with no issues.

My Samsung S21 has no issues live viewing while connected to either cellular of WiFi.

Is there a new compability issue with the Google Pixel 4 and the main Ring app? Anyone else?
