Just updated my software to iOS 13.0 and now my FR635 will not alert me of text notifications. When I receive a text my FR635 does not buzz or even show that I have a notification. When I receive notifications from other apps (twitter, groupme, etc) my FR635 will not buzz but with show them on my notifications widget. The only thing my FR635 will do still is buzz for incoming calls.
I saw other people with similar problems and tried going to settings -> notifications -> connect -> show previews -> always, but this did nothing for me. I still do not get notifications for texts at all or any vibrations for all other notifications (besides phone calls). I have phone notification alerts set to vibration for both during an activity and not during an activity through the Garmin app.
