**Screenshot or video of problem:**

**Additional information:**
Steps to reproduce:
1. Open Companion app -> Settings -> Companion App -> Manage Widgets
2. Configure a new widget
3. When prompted to "add to home screen", **DO NOT** drag the widget to the home screen. Instead, click the "add to home screen" button.

Result: The widget has been created in the Companion app, but *was not* actually added to the home screen. As a result, the widget cannot be deleted in any way, since the only way of deleting it is the home screen.

Suggested workaround: Since this is likely rooted in a deeper problem in Android, a fix would be to provide a way to "re-add" the widget to the home screen when updating it via the app. This way, if a ghost widget is created, it can still be properly added with the right steps.
