Account linking problem

Hello, I bought Infinite Flight Pro using my mother’s Google Play account before creating an Infinite Flight account. Later I created my Infinite Flight/community account with the username 7708E542.
The Pro subscription exists on the Google Play account, but it is not linking/restoring properly inside the app. I tried restoring purchases and signing in again, but it still does not work correctly.
I also want to log in and use my Pro subscription on another mobile device, but I cannot do that because the subscription/account is not linking properly.
Please help me link the Pro subscription correctly to my Infinite Flight account and allow me to use it on my other device.
