GMS 2 How to restore acknowledged IAPs in 2.2.4 on Android?



After struggling for days I finally managed to get IAPs to work in 2.2.4.

I'm facing an issue now that if you already own an non consumable IAP, reinstall the game and click the "buy button" again, how to restore that purchase in 2.2.4? Those purchases were automatically restores upon clicking the buy button in pre 2.2.4.

I have checked out the Google Play Billing Manual that came with Google Play extension and GMS2 guide "Android: Google Play Billing (IAPs)" thoroughly but didn't find any tips.

Using IDE and runtime

Thanks in advance for any tips! :)
