Hello. I use gmail mail app client on my imac. When I click on the message in the email inbox, the mail message takes a very long time to open, and then even longer to open the attachment after I select open attachment....
Why is it taking so long? I can only read the subject header of the mail message, no other content - it takes about 20 minutes (twenty minutes) for the message to appear on the mail message screen. Please help.
iMac 21.5″, macOS 12.6
