Only when the users actually put in .comr or .cm instead of .com and they can not login
In terms of your change of domain name, was it just simply changing the custom domain in the same app?
Had your users ever updated their own passwords and were logging in through the traditional manner of username and password or are you continuing to send links for them to login?
You should test by signing up and see if you can then login as a user normally would. Then test by creating a user and sending the link for them to login for first time…if both are working, then the issue may be related to just the old users.
Then I’d test by having an old user request a password reset link…if that fails to find the user, then I’d report to Bubble the bug that the users of your app are not found, only after verifying you don’t privacy rules affecting things for users.
