Log in to Locus Store is required when you need to purchase and download products (maps, routes, features, graphics…) from there. The process is pretty simple, just choose among logging in via your Google or Facebook account or enter a common e-mail. However, there are situations when the login process is not successful:
If you have a Gmail address, you have also a Google account. Use the Google button when logging in the Locus Store.
If you use MicroG and you don't switch off using Google Play Services for login in Locus, it may happen the login is not possible.
