IMAP Synchronization with server fails
Since upgrading to 15.4 and also in 15.5, I am experiencing a lack of synchronization of deleted and read messages. When I delete the message on my iPhone, it no longer deletes it on the mail server. So I end up having to delete the same message again on the server. This used to work prior to the upgrade. The same issue exists with marking the message read. It no longer synchronizes with the server.
