yeah exactly. On mbin it works this way and lemmy inserting the link breaks that. But it does it for communities in the community description sometime as well, though I don't know if it is just a user "error" or a lemmy error

Yes they are, but you have my profile on your server and you do not need to leave the server to view my profile... @ user @ lemmy.instance should link to https:// mbin.instance/u/@user@lemmy.instance and not to https:// lemmy.instance/u/user

Actually that behaviour is very annoying to other platforms. Mbin for example can only link to the lemmy server this user is on and no longer the local profile of that user. Example: @ user @ lemmy.instance gets converted to [@ user @ lemmy.instance](https:// lemmy.instance/u/user so on mbin this does not open the profile of the user on the local server, but instead links the lemmy instance, so you leave your instance to view the profile.

(spaces included so this won't get converted to mentions, etc)

iodéOS here and I can't find it on my phone either (yes I looked at the system apps)
