fix fix fix ability to delete an email one time only
delete the same email one time only to include all of my devices and one time only on desktop. And don't undelete items automatically I've checked to delete. you are just unchecking them So awful. I"m guessing gmail doesn't do that.
And yes,I"ve already asked AOL support about deletion on one aol app does not delete on all aol apps on other devices. No solution.

If you are using multiple email clients, in order to make sure that the mail settings are synced between devices, you need to make sure that your devices are set up in IMAP, not POP. Here’s more info on this: https://help.aol.com/articles/what-is-the-difference-between-pop3-and-imap
