Difficulty logging in consistently, often need to reset password, am often late consequently.

Hello!

I wonder if you can help?  I have a Pro account and encounter regular problems with logging in swiftly.   If I start a new meeting and wait the guest receives a 'host is another meeting' message.  If I wait until I get an email to say they've arrived and then click I get asked to log in and quite often the stored password is wrong and I have to set a new one which makes me late for the meeting. Any thoughts?   Are my settings wrong?  I can't believe it's meant to be like this.  

Advice gratefully received.  Thank you!
