So is anyone having issues making video calls via Google Duo? So far I currently have issues on my Galaxy Note20 5G, Samsung A20, and Galaxy Z Flip. Called never connects.
If you are experiencing the same symptoms on three different devices, I would try reaching out to the developers of Google Duo to see if they can assist with any options for you.
You also have an option to try clearing the cache/data on the Google Duo app to see if that helps any.

Also, make sure your devices as well as the Google Duo app is up to date with the latest software.
