Blank User Created on Sign up

This seems to have been a bug before and has suddenly appeared in our app - (Error In Signup Screen)

Urgently need confirmation on how to fix this or if it’s a bug with Adalo.

On sign up there is a blank user created with only their email and the error message - same address or empty address, we’ve changed nothing in the sign up process.

Only seems to be an issue on iOS, please help.
