I rotate between 2 Garmin watches - an Instinct 2X and a Fenix 7 Pro. The Fenix is my primary wearable and primary training device. Whenever I change my watch during the day, the floors climbed using the earlier watch say in the morning gets deleted on Garmin Connect. This has been frustrating as I have a goal and the daily, weekly and annual data is no longer valid. As many others have described I do have incorrect readings but that by itself is not a major problem as is the deletion.
