Essentially the apps have same package name but different signatures and the app store that installed it should be the only one to recognize and update it.
But Google is likely trying this dark pattern to sway people away from F-Droid or alt stores by making users uninstall these apps and install it from the Google Play Store.
It’s been going on for a while and is annoying af.
yea, and people here suggesting f-droid to change package names are crazy. F-Droid’s goal is not to mess with developers code at all and provide builds as is from the source code.
