Garmin 645M updated....and now simple heart doesn't work

My watch updated last night, and simple heart doesn't work.

It shows IQ!

How do I fix this?

Watch on/off doesn't help.

Uninstall/re-install didn't help.

Connected to computer doesn't help.

Any other ideas?

  • Simple Heart is one of mine.  Did you try to use "Contact developer" to contact me?  That's the best way.

    Try rebooting the watch.  Press and hold the middle left button for about 15 seconds, and the watch will turn itself off.  Then turn it back on.
