Sorry, but how can I upload screenshots?

Hell Korina, thank you for the answer. If I try to log in to windy maps with the correct login data from Windy, I get an error message (see screenshots)! If I try the function "Forgot password", I get the error message email - address unknown. If I try to re-register with my login details (from Windy), I get the error message that the username and email have already been assigned.
Sincerely,
Andreas Wagner

Hello, maybe the question has already been answered, but I have not found it. I installed Windy and added an account. After that I installed Windy Maps and wanted to use this account (Windy) for the Windy Maps. When I tried to log in, I received the error message "incorrect login data". When I tried to reset the password, I received the error message "Email address not known." When trying to use my user data (from Windy), I received the error message that they are in use.
I uninstalled and reinstalled the App twice, but nothing changed.
