Garmin ForeRunner 245 Music, software version 13.00 e80dcb4.
For any calendar (Google Calendar) notification, my forerunner will repeat the notification until I dismiss it manually on the watch, even if I've responded/dismissed it on my phone (Android, Samsung s23).
As an example: Let's say I have an appointment at 11:30a. If I don't dismiss that notification on the watch, then when the next calendar appointment notification occurs (e.g. an appointment at 12p) the watch will notify me of both the 11:30a AND the 12p appointments. It will continue doing this repeatedly until I go in and manually "Dismiss" that notification on the watch.
Less frequently, it will do this (repeated notifications) when notifications from other applications occur (text message notification, Signal notification, etc).
Any ideas on what might be happening? or steps I can take to further debug?
