Not attive pro on smarphone

Unfortunately, even today I encountered the same problem here is the image of the error that does not connect my account avg ultimate

Daniel,
Your AVG Ultimate will get activated using your email address and password registered with AVG. We have removed the Activation method of invitation code from new version. I request you to uninstall all old versions from your Android device and reinstall it from Google Play Store. Try to activate it using your email address and let us know the status.

Thanks, I did what he told me but gave me the same answer on that device. The attempt to log in with my account replies that the first installation on that device is not valid. The smarphone runs android 8

Hi I can not log in with my pro account on the smarphone, it returns me the message connection failed, it gives me the possibility to use an invitation code

Thank you for the screenshot, Daniel.
Can you translate the error message in English?
Are you trying to log into AVG my account through this link: https://myaccount.avg.com/my-account-login ?

Thank you for the information.

On the site I can log quietly. The error message says: "Sorry, authorization failed"

Unfortunately, before contacting you I made 3 attempts of the proposed method. but I will return. Could it be a problem to have the account on 5 smarphones of 3 different versions of andorid active?
