I just faced the following problem. I have an account and I've been logged in for months (or years) on my mobile. Recently I changed the mobile and I tried to login on the new one to WindyMaps. I know the username (I can see it in WindyMaps on my old mobile) but I don't remember the email address I registered with. Therefore I suggest one of the following solutions:
- Present email address in the mobile app (next to the username) - recommended
- Enable password reset using the username
PS. I might overlooked the solution/workaround - if so please let me know.
