How to fix a BM-CPH-08 error on google play store 

Answer 1

I have experienced this problem when it comes to making a purchase from Google Play Store when connected as a gmail account / google hosted.

The problem was that Google Wallet service has not been enabled for the user / org / domain that I was using to make the purchase.

I activated the service of Google Wallet, access the management console as the administrator of the parent domain [1] -> Other Google services -> Replace the filter if necessary, disabling "Show top offered services" in order to show all services -> Google Wallet -> Click the drop down menu under the shopping cart icon and configure accordingly.

===================

[1] Note, I connected at first as a user of the organization who was also a domain administrator, but for some reason did not have full access to the functions of the management console. It was necessary to log on as the administrator of the original domain to see the "Other services Google" console item

Answer 2

My problem was that I had school google account linked to my phone, plus regular gmail account. Although he assured me that my Google Wallet, Google Play, and the game itself were linked to my normal account, apparently, that had a school account (which does not allow transactions) linked to my phone Indeed, so I could not buy the game.

What finally worked was to enter setup / accounts / google on my phone and the elimination of school account. Then I started the game and was finally able to make a purchase. Then add the account to school again after purchase and tried to make a purchase again and of course I got the same error message "Error google game CPH BM 08". So I'll have to delete the account from my phone for every purchase I guess.

Also, updating Google Play did nothing for me. I would look into their Google accounts first.
