Can't send mails from android app

I try to send the token from the app but it tell me that it can’t for a unkown reason ( I can’t see the rest of the sentence ) so I try to disconnect and try the forgeting password it say it can’t send email.
I don’t know how to connect the app and properly try my sketch.
Thanks in advance.

Hello, Fixed. But you need to wait for google store update. Sorry for inconveniences.
