AOL email on I Phone and PC does not synchronize
I have an iPhone SE 2020. I use AOL mail on my PC and on my I Phone. In settings on the I Phone, the mail account is set up as an IMAP account. Here is the issue. When I send an email from my phone it shows up in the "Sent" items on my computer. When I send an email from my computer it shows up in "Sent" items on my phone. But when I delete an email on either device, the deletion only occurs on one device. Can you help me synchronize my I Phone and PC so that deleted mail in one device is deleted in the other?
