Live view won't load

I am here seeking help because I've literally tried every possible solution I can think of and nothing is working. I have 2 spotlight battery cams and 1 doorbell pro. One of spotlight is at the backdoor and the other one is up by the garage and the doorbell is by the front door (obviously). The backdoor and doorbell works flawlessly. The spotlight cam at the garage though consistently has connectivity issue where it doesn't load the live view. I swapped out the ISP router/modem combo and got a mesh google system which helped for a few weeks but eventually that was short lived. Next, I moved one of the Google mesh point into the garage. It's literally within 5 feet of the camera and the RSSI is at -36. I tested my internet speed at the location of the garage cam and it pulls 250 Mbps download speed and approximately 30 Mbps upload speed. I tried a hard reset (holding down the top button for 20 seconds), I've also removed the camera from my account and reinstalled it, and lastly I deleted and reinstall the apps (rapid ring and ring app). I did all these troubleshooting multiple times and the only time it seem to work if I move the camera inside my garage. But that really defeats the purpose of a security camera that I want to use outside. It's weird because the doorbell pro works great and it's about equal distance to the main router. Any help or suggestion will be greatly appreciated. Thank You.
