Zoom app says that host is in another meeting when I am not in another meeting.

I'm having the same issue and have an important forum coming up next week.  This is not good at all.  Sometimes it says the host is in another meeting, sometimes it has participants waiting.  I did not set up a waiting room and cannot let them in.  I noticed that when I end the meeting in the Zoom app, it still shows the meeting is in progress on the Zoom website.  Hopefully, hitting end there will help.  I have not verified that yet. 

I m having the same issue....
