I migrated to AOL from Verizon when they stopped handling emails in April 2017.  From time to time I got duplicates but the problem now is much worse. I also have missing email for about 2 weeks. Problem started mid November 2019. Lots of emails are in my inbox over 345,000 today. Have at least 5 or more of lots of emails. My settings are correct. How do I fix this problem?
