I cannot log in to the app. Why?

The authentication system for the Assimil e-course is based on the services offered by Google.

Access to "Google Mobile Services" (GMS), and to Google services in general - whether on computers (Windows or macOS) or on smartphones and tablets (Android or iOS) - is therefore mandatory in order to be able to log into the app and access the full version of the method.

Accordingly:

- Your Android smartphone or tablet must be compatible with Google services and apps; some smartphones lack Google's services, such as some Huawei brand devices for example.

- You must log on from a country that does not block or censor Google services, such as China.
