Forerunner 945 - Disconnects from Connect App on Samsung Galaxy s24 ultra

Every time I pick up the watch after being away (not home) even for just 20 minutes, the Garmin Connect app shows the device as no longer connected and I have to re-connect the device with the PIN and the entire setup process as if I was connecting it for the first time. The app shows the watch under devices as Registered to Garmin Connect, just not registered/connected to the phone.

This is frustrating as it also drains the watch battery and I can't rely on being able to pick up the watch and go for a run/ride/swim without planning to make sure I re-connect/register and charge the watch.
