Comcast mail loading very slow on iPad and iPhone

For the last month or so, email is taking forever to download.  My devices are running on the latest iOS and my mail setting is on IMAP.  I have tried to delete my email account and reinstalled it, but no help.  Some people suggested turning the iPad off and restarting.  No improvement.

An iOS 18 issue and incompatibility with Comcast’s mail?

supposedly Apple is aware and the latest versions of iOS 18 were going to provide a fix….but no.

Anybody know about a way to fix this?
