New Post: Error when downloading messages by Uid()

Without changing anything, now I'm able to get the messages by UIDs

Actual problem:
if I get messages by UIDs, I get a [READ-ONLY] session (please see log below), so I CANNOT mark as SEEN.

If I Download the UNSEEN messages, then all is ok.

Any suggestion ?
