I have just set up new Google Account on my tablet that uses new Google Play account. I want to add another Google Account that I use as main that already has history of apps I bought in the past and payment method associated with it.
So instead of using new Google Play account with no track record and bought apps, I want to remove it from existing Google Account and link to it established Google Play account.
How to do that without adding another Google Account to device only to have everything synced and mixed up? After all this is short term purpose because after adding apps I already bought, will mean removing that Google Account and switching back to previous. What if I want to download paid application again? Here we go again..
