No longer connecting to Jabra elite 65t active

While these headphones have worked nicely for weeks (and still work for listening to podcasts using a smart phone), they don't connect to the Forerunner 245 since the update to 4.10. became available.

  • Installing the update itself didn't help
  • Additional reboot didn't help
  • Removing the headset from the Music settings didn't help
  • Restarting the phones didn't help.
  • Tried several combinations of the options above for an hour. No connection
  • FR245 also doesn't find any other Bluetooth headphones any more.
  • FR245 still connects nicely to phone, though.
