Play Store updates/installs app using a different

问题:

On this bug report on github https://github.com/googlesamples/android-play-billing/issues/2#issuecomment-305380836 we were asked to raise the issue here.

The issue is simple. User has 2 or more accounts on their phone, let's say [e-mail] and [e-mail]. They install an app with account [e-mail]. They purchase some IAP item. The app updates and now the app is under [e-mail] and the user has lost the purchase. This happens a lot when using staged rollouts.

Main issue, as developers we aren't allow to let the user choose which account to buy with or which account to check for purchases with.

Second issue, the Play Store app on Android ignores the user account selected on the hamburger menu. The only workaround for this is to use the Play Store website as described on this workaround https://github.com/googlesamples/android-play-billing/issues/2#issuecomment-259108286 on the same bug report.

I don't know what the ideal solution is, all I know is that this is a huge hassle for developers leading to a lot of 1 star reviews after each update.

EDIT: As pointed out on a comment, when I refer to multiple accounts I am talking about multiple Google accounts for a single Android User, I am not talking about multiple Android users within the same phone.
