Thank you very much for sharing this video with us.
I’ve tried to do the same on one of my boards as well, and it’s completely the same: I just can’t put a comment, no matter what I try.
I’ve reported this immediately to our devs. They’re on it. I think it’s the case with longer texts (such as emails, like both you and me tried). However, we’ll fix this ASAP.
Thank you very much! We definitely couldn’t do all of this without you.
Have you fixed this? I just pasted a long email in no problem.
