I had the same issue. Here is what I did that worked.
1. Go to the phone app and uninstall the Agenda app.
2. Restart the Sense.
3. Close the app on the phone and restart the phone.
4. Open the phone app and then re-install the Agenda app.
My Agenda app on the Sense worked after that.
Hope this works for you too.
