I have uninstalled and reinstalled the app. I have removed and reconnected my 220. The watch will connect with the app, but it won't upload the new activities. Any suggestions? Attached is a screen shot of the error that is occurring.
Which version of the GCM app are you using? In Settings, App Info. Older versions don't work with all devices anymore.
There may be a corrupt FIT file on the watch. You can try to rescue files from the 220 (USB cable) and then delete all the history on the watch, then record a test activity and sync that.
If that still doesn't work a master reset of the watch may do the trick. You will probably lose all settings/stats though.
