Do they not already? I'm fucking tired of the Play Store "updating" the sideloaded version of the Kindle app (the one that comes from the Amazon App Store and lets you actually buy ebooks) to the version on Google Play (which only lets you read ebooks you bought outside the app).
Nope it does it in the background all on its own and it completes it just fine unfortunately. I found how to disable automatic updates for a specific app now though, so at least I won't have to worry about it anymore.
I don't want to disable all automatic updates though. I still want my apps to update, I just want the Play Store to stop updating the one app that the Amazon App store should be updating because the version the Play Store installs every time it does is worse.
