Try looking in IDE > Locations > devices for any phone presence that may have a device type other than placeholder… i.e. mobile presence sensor. Some users mentIoned they did not see it in IDE > Devices but did under the locations section. If you do find something… don’t delete it immediately. First remove them from any automations set to use their presence, disable get location from their phone for that user, log them out of the app. Then you can remove the rogue presence sensor for them.
Log them back in, enable get location and set up the automations again.
