Recently updated to Tizen 3.0 on Gear S3 frontier, and had many of the same issues as other users. After installing, and re-installing both the Facer app, and the Facer Companion App several times, my watch face (TL Urbane-LED) started working correctly, except the phone battery level does not update. The phone battery level will either not appear, or it will appear when the watch face initially syncs with the phone, but not after. For example, if I choose one of the default Samsung watch faces, then choose my Facer watch face, the phone battery level is displayed as two dashes (–) and never updates, or it will display the current phone battery status, but that percentage will remain the same throughout the day, even after attempting to re-sync the watch face.
Help, please. This is frustrating!
