Connect App -> Devices takes ages to load

When I go to "Garmin devices" in the Connect App (4.24.1 on OnePlus 6 Android 9), it often takes 1 min or even longer to load the device list. This started with adding the vivomove Luxe. There's only an Edge 520 as another device in the list; with my "old" vivomove HR (which I already deleted), it loaded the list in seconds.

Anyone else?
