Unable to load your home solutions / SHM broken in Classic App (August 25, 2020)

[jlv]

The migration doesn’t affect your devices, and only changes a small subset of your account. See this for details:

What happens when I hit the Migrate button

It converts routines to automations/scenes in the new app. It converts SHM and SHM rules to STHM and automations/scenes. It migrates smart locks over to smart lock guest access. You would lose the ability to use routines, and SHM in the Classic app. You also lose the ability to edit scenes from the Classic app. But you can continue to use the Classic app to control devices until the app is shut down in the coming months.

After the migration you can continue to use the Classic app (until it is turned off), with the restrictions noted in that post.
