Play Store version 38.8 has been released, and Google will add the ability to remotely uninstall apps from devices connected to the same account. The remote offload feature will be available on all platforms - computers, cars, phones, TVs and wearables.
Currently, you can only install apps on devices under the same Google account, but you can't uninstall them. The new PlayStore's new UI compiles all installed apps into a more manageable list. For example, you can sort by size, group by device, etc.
This may be particularly useful when managing AndroidTV, AndroidAuto, or WearOS apps, which have more limited interfaces. It will be more convenient to install and uninstall apps using a desktop browser or Android phone.
The new version of the app isn't available to all users yet, so it might be a while before you get the latest features.
