Teams Click Here to Join Missing Now

There used to be a Click to Join button on our Teams walkup system that would allow anyone with a Teams meeting ID and passcode to join any Teams meeting. Now that button is visible for a slight second under the Get Started button and then disappears. This just started happening and it is driving me crazy because I can't figure out what happened. I have reinstalled several times, removed cache, looked all through the registry, etc. Anyone know why this just started happening?
