Yes, force open

What it is

The red button under the force-open warning on the This project is busy screen.

What to enter

Nothing to enter. It is a button you press.

What it changes

It takes the project from the other session and opens the saved copy for you (You now hold this project). The other person is told their unsaved changes are not saved and is sent back to their project list. If the project became free on its own, it simply opens. Nothing in the house changes. Nothing in the app changes.

If it goes wrong

If it fails, you see Force open failed (number) and go back to Your projects. Anything the other person had not saved is lost; talk to them first if you can.
