Thanks for looking into this.
I just wanted to add I'm having the same problems with my Gear S3 and Galaxy S8. No temperature, sunrise/sunset.... that sort of thing.
Changing to a Samsung face and back to Facer does not fix the issue.
The missing data does display fine in the preview window through the app.
I've uninstalled both the app and companion plugin app, then reinstalled both, resyncing all faces--still didn't work. Both apps are up to date.
