Do you have an Android phone or tablet? You should be able to buy algorithms in the H9 Control app on an Android device.
I've never used Google Play credit but I suppose you should be able to use the credits if you have added them to your Google Play account.
Yeah, I’m using my phone for H9 Control.
I just want to be sure that some of the options of payment work before I buy algos, as my income is not steady (Third World problems, lol).
