If possible, inform user about Connection progress. That is, "Waiting for meeting to be started", "Waiting for admission", "Asking to record meeting", etc.

For example, when vMix restarts after a settings change it is easy to forget that the host must admit the vMix participant. Instead one gets an error message after a long time...

Or, worse, if vMix is joining a meeting in someone's Personal room with the proper credentials, the Zoom Input/s is/are just blank until the meeting is started by the host.

Also, sometimes when the Meeting ID does not exist the response in the Input/s is/are first "Connecting...", then followed by "Click here to Connect" without any error message.

A few times, after clicking "OK" in the Connection (or "Zoom setup" window), I got an error message in the first Zoom Input and the other two Zoom Inputs displayed "Click here to Connect". I have tried to replicate, but I have experimented with so many variants (Personal Rooms, bad/missing ID/pw etc) that I do not remember which combo caused that behaviour.
