Live view is not working on all cameras; everthing else is working

I have one Ring Doorbell Pro and two Indoor Cameras. Since a few weeks, the Live View on all three ring cameras stopped working. I cannot figure out why, because absolutely nothing has changed. The alerts and recordings are still working, Snaps are updated every 30 seconds, however, Live View does not work on all the cameras. I have looked online for all sorts of solutions and specifically checked the following. The problem still persists. Can someone help me solve this? I have already tried: 1. Switching networks from 2.4 Ghz to 5.0 Ghz and vice versa 2. Rebooting router 3. Tested internet speeds 4. Have ensured that no VPNs are running 5. Reset the device by pressing and holding the setup button for 30 seconds 6. Removed the device and then re-setting the device up 7. Testing Live View with device next to the router. RSSI is in -40s 8. Devices are all wired and voltage is good 9. Removed the app, rebooted phone, reinstalled the Ring app 10. Tried on Rapid Ring and through the browser. Same issue 11. Tested on Wifi at two different locations and also through mobile data 12. App/OS software is updated to latest versions Edit: Level 2 support tried but couldn’t offer a solution.
