Logged out after EVERY meeting

I usually stay logged into Zoom because I am in it frequently. Previously, I would have to login after being logged out automatically every 2-3 weeks. Lately, I am getting logged out automatically after leaving each and every meeting. I don't understand. I'm just leaving a meeting and nothing else. But, when I go to join another meeting, I have to log into Zoom because I've been logged out. Any idea why this is happening? And, what can I do about it?
