@pfxdona@Roman21630442@Mobvoi_Official@MyHiit@Stephhh39725463 I had the same issue. Tried phone on/off, watch on/off, phone BT on/off. Nothing worked. You will notice the problem is that the TicExercise app is stuck at uploading the WO. Somehow flight mode on/off on the watch makes it stop the upload and try again.
