The display name you are choosing is probably invalid maybe because it's too long. Try using a shorter one.
Ayy I got it. Thank you! I have now become Tovarish Tomato, the user of alliterations lol
I was also trying to do this recently with no success.
Hexbear users can’t change their display name at all because of the pronoun tag system
Ah, damn, that's what I suspected. Thanks!
It might be too long, but also note that some special unicode chars are not allowed, and these are used by some emojies (e.g. flags). That @ may not be the first char. And that it must be at least 3 chars long.
