I have had my Forerunner 245 (not the music version) for 1.5 years and it is mostly always painfully slow to sync my workouts to Garmin Connect. It can easily take 20 minutes or more to sync a 40 minute workout. On a very rare occasion it will sync within a minute but that is a very rare exception. I thought it might be my old iPhone 6 but I've had a iPhone 12 Pro with latest firmware since October 2020 and it is no faster to sync on my new phone. I followed all the pairing advice published by Garmin but that doesn't seem to help. Any ideas?
What makes me jealous is I know when my husband is home from a run because I get a notification to like his run before he is in the front door (he has a Vivoactive4 with Android).
