First of all, awesome work with this plugin. Thank you very much.
Now to my issue: I built an account system using firebaseV3. Everything works fine, users can change their displaynames and password, all good.
Except the fact that the event "On profile update error" doesn't seem to trigger when the display name that has been entered in the "Update profile" action already exists...
To test this, I created two accounts in firebase and changed their usernames in my C2 program. And even when I choose the display name that the other account already has, it changes the display name.
Is that intended?
I thought that the "Update profile" action would prevent same display names.
