App not launch due to licence validation

Hello,

I have a problem with an application. (a game for children, “squad busters”)
I was able to install the game with App Lounge in anonymous mode.
But when the application launches, it says that it can’t verify the license and that you have to use the google account that was used to install it…

e/OS/ v1.21, Android T(13) on Poco F3 (alioth)
Microg is activated, the play store service is activated too, but I don’t want to attach a google account to the phone. (In my opinion, it’s the basis of a de-googled phone).
So is there a workaround to solve this problem of validation, without attach a google account ?
Thanks

No. Licensing is obviously tied to a Google account used to purchase said app/game.
If you insist on being fully de-Googled then know you cannot use purchased and licensed apps.

That’s not entirely true as a lot of paid apps are ‘pro’ versions and don’t do license checking but you still have to use a Google account in App Lounge or Aurora Store to download/install them.

The Play Store service you enabled of course would require a Google account to be able to verify the license. There is no workaround and it is technically not a problem.
