User story: N/A
We have this:
[Tested on Beta] When a user is on the Describe step, if a user enters a caption that exceeds the character limit, they get a warning. However if they edit it, and it is still too long, they do not get another warning, resulting in an error message when it confirms what's been uploaded successfully. Not only that, but as described in T222481, the user is not able to get to the next step (Add data) at all.
We want this:
A user should be warned before publishing files on the Describe step that the character limit is still exceeded.
