i'm not a host when the meeting i'm create

I know this is an old thread, but this just happened to me today (a very important meeting), launching the meeting from the calendar URL, which opened my fully-updated client which was logged in to Zoom with the correct email address (the only one I ever use). But I was not the meeting host, and the "claim host" button in the meeting did nothing.
Fortunately, no one else had joined yet, so I was able to end the meeting and login to the web account and edit the settings. Everything looked OK, so --as a backup-- I set myself as a meeting co-host, saved changes, then I started the meeting from within the web interface, and I was then the host, as expected. 
This was really scary, especially since it was absolutely essential the meeting was recorded. 
I wanted to add to this discussion to make sure it was known that this DOES happen, and I am an eight-plus year Zoom Pro user and account admin, so I know what I am doing. 
I understand that glitches happen, but the system should be smart enough to proactively assign a valid host in the event it hasn't recognized that at the start of the meeting-- something like "there's no recognized host, but the person who is in the meeting matches the person who owns the meeting, so assign host to that person immediately."
Thanks for listening.
