Hello Samuel,
I'm contacting you regarding a case we had open about an issue when adding multiple alerts to the fenix 5x. With the update to 9.00 software that issue should have been resolved. Can you let me know if you continue to experience any issues specifically related to the alerts?
Thank you for choosing Garmin,
Joey
