With the new firmware update I finally decided to try out Fitbit studio. After creating a project and loading the watchface onto my Ionic I couldn't change back to a different watchface. Is this a known bug? I tried power cycling both phone and watch and it still wouldn't change. I had to do a factory reset. I do not want to have to do this every time I load a watchface using Fitbit studio.
Go to your fitbit page on the app, which has the clock faces, apps and media etc, then go to developer menu, the clock face should be listed at the bottom, click delete app then it gives you a normal clock again! Hope this helps 🙂
