That’s really odd, have you tried logging out of the browser account and clearing your cache?

@Frank Thun -

1. Is it only happening with this board or with other boards too?
2. Can you try it with the Miro desktop app and see if you get the same message?

@Frank Thun - While you are not pasting, you could be running into a limitation based upon the formatting you are applying (bold, lists, etc.).

Have a read of this reply by Miro support:

If formatting is the culprit here, the error message could use some rewording to improve the user experience.
