We are building a mobile app that uses PKCE flow to authenticate. However, if the user chooses to create a new account, they get an email sent to their account for verifying their account.
When the user taps on that email either on their phone or from their computer, they get a blank screen. This usually confuses the user, and so they go back and click the email again, now leading to a 404. This then leads to complaints that the registration wasn’t successful, but it turns out that the first click of the link actually was successful in activating their account, but the blank screen caused confusion.
Can someone please explain to me if i’m doing something wrong which causes that blank screen, or if this is a bug?
