HELP! Pro account is only allowing 40 minute meetings even with license assigned to single user

Yes, I have seen this posted several times in the forum but am at my wit's end trying to solve this.  I am a single user on a Pro account.  I upgraded 5 days ago, and today was kicked out at 40 minutes.  After searching the forum, I saw that the license has to be assigned, which I see is applied to my single user.  Does anyone have any other troubleshooting tips?  I see 90% of my clients over Zoom and this is killing me!
