I can’t confirm when it started breaking as non-English characters are a bit rare in our workspace, but the last successful one I can see was Dec 31, 2024.
I ran into the encoding issue as of Feb 17, 2025, potentially earlier.
So that we can look into this further would you be able to please fill this form adding as much information as possible to it (such as account ID, board IDs, item IDs, timestamps, etc.) so that our team can take a look into it?
