    now when we update and card that has a @mention in it all the other users will see the card turnicated...
    so lets say 5 comments down on a card with 10 comments has a @mention i need to edit.
    when i edit that comment i can see all comments on that card but other users cannot see that comment or any older comments just comments newer see photos... light mode is me editing the one comment with a mention and the dark mode screenshot is the other user. so you can see on the lightmode screeshot i edited a comment with @brian to say "@brian Brian test" now the other user cannot see any other comments from that day.

    Do not know how or why but one of our users (out of 15 or so with 7 active every day) is able to do @mentions but no one else? going to do more testing.

    Hello,
    I’m having an issue in Nextcloud Deck where I cannot post a comment if I mention another user using @username.

    When I write a normal comment (without any mention), it works fine.
    But when I try to tag someone — for example @ali Mirjalili-ADM — the send button doesn’t respond and the comment is not posted.
