C4 Backup restore to C7 weirdness (AKA you should reboot after a restore)

So in the light of my mesh failure I thought ok time to start the migration so I restore the latest C4 backup onto my new C7.

In the dashboard app it asks me for my Life360 credentials and none of my dashboards show up. I don't have life360 installed, don't need it, don't want it so why am I being asked for this just to set up/restore my dashboards?

Well it turns out that many of the apps got messed up in the restore and started pointing to different apps. Fortunately a reboot solved this but it's not stated anywhere in the docs this is necessary.
