We are aware of the problem with the application using Gmail API. We are looking for a quick solution to this problem, and in the meantime we recommend using alternative methods of sending to e-mail: SMTP or through our server. Sorry for the inconvenience.
This problem occurred due to updated Google requirements for authorization and authentication methods in Google services (https://developers.google.com/identity/android-credential-manager?hl=en). This allows you to separate the areas of the permission request and you will not have to provide access to e-mail and standard permissions in the future if you have not authorized through Google in the application, but only want to use the GMail API. Simply put, it is much more convenient and understandable for the user, only the permissions that are necessary for a specific function of the application are requested.
However, this led to problems, since the methods for supporting such functions and sending e-mail via GMail API do not exist in the required volume now and we have to use "crutches".
We will try to solve the problem as soon as possible.
