“You cannot install this app because another user has already installed an incompatible version on this device”

Question

Trying to install my own app from play store, it says \"You cannot install this app because another user has already installed an incompatible version on this device\"

Answer 1

Update to Preethi Rao's Answer.

From Android O this option is available under

Settings > Apps & Notifications > App info

There you can see your uninstalled debuggable app with label Not installed for this user.

You can open it now, and you can see triple vertical dot in top right corner.

In that there is option Uninstall for all users. By taping it you can uninstall the app completely.
