Can't Add Attachements to ArcGIS Pro Feature Layer

[LonerockAdmin]

Currentently one of my users above has Add Attachments Greyed out on his Machine but on my computer I could add it just fine on my account and his. Another user sharing the same account could do the same. Any ideas why one user would have greyed out but not the others? (The attachments in the file had to be added by another user.)

Ill try the publisher role. Since we do not have any more current licenses for a higher tier than standard. Thank you for the suggestion.

I don't think it is permission-based. I just checked the other computer that can do it. It's the same account, and it works just fine. Maybe it's something with that computer, and we need to reinstall or update ArcGIS Pro on it.

After trial and error, I updated to 3.3, and it worked fine. I'm not sure what the difference between 3.2 and 3.3 is with Attachments, but it's not allowed. (When it worked fine a couple of weeks ago).
