Where can I find the option to sync automatically or set the sync frequency for Garmin Epix Pro Gen 2? I can't find it in the Garmin Connect App.

So the battery settings were already fine. I still have the same question as it's only syncing when I refresh on the app. I want to be able to set the sync frequency. It doesn't seem to be syncing automatically at all. What is the sync frequency supposed to be if you say it syncs automatically? Where can i find these settings. My cheap fitbit did sync automatically. I wasn't constantly refreshing any app. My question hasn't been answered 

Then I suggest you contact Garmin support. Because for most (almost all?) of us, the sync happens automatically without problems. You cannot (to my knowledge) set the sync frequency, but based on my experience and how I interpret Gamin's fit file contents, my Forerunner 965 syncs every 240 seconds (= 4 hours), or every 2000 steps, or whenever I stop an activity. I'd expect Epix Pro to behave similarly.

Oh, one more question: You don't happen to have battery saver mode activated on your phone? That limits apps' ability to sync in the background.
