Hello, OLEG5454 .
We are talking about the fact that you are not logged into Google Play under your account.
In this case, the problem is not with the application, but with the logins to your Google Play account on your smartphone. Unfortunately, we cannot help in this case.
As far as we understand, you need to either create a Google Play account and link it to your phone, or simply log into an existing Google Play account.
If you have any additional questions, do not hesitate to contact us.
