Can't change administrator UserName in Omada Controller software
In the Omada Controller software, from Controller Settings > User Account > Edit User, I'm unable to edit the UserName (that is, the field is disabled for editing) of the sole administrator account I created when first configuring the software.
If I create a second administrator, log out, and log into that new account, I'm still unable to to edit the UserName for the original account.
And after doing that, there's no delete button (trashcan icon) for the original account, either, so I can't migrate to a new administrator account with the correct name as a way of getting around this without leaving the original administrator account active.
I don't have Cloud Access turned on right now, nor can I think of anything else to which the original administrator UserName might be bound, as justification for not being able to edit it.
Hopefully, I'm missing something obvious. Any thoughts on what I can do to get around this? Thanks for any help!
