My Wokamon has been stuck since late last night saying I need six more steps to the next level. Every time I press the heart/sync button, instead of instantly syncing like it used to, it now just starts to spin. Will keep doing that for about a minute, at which point the app just crashes and closes itself.
Today it keeps freezing when I try to sync Health App steps in the phone app, but Watch app shows updated steps
Have you tried to turn off and on your phone?
