Dexterity

So earlier last week I was getting low battery low memory messages from my watch.
So on Thanksgiving morning I fumbled with my mini screwdriver and the mini screws on the back of the watch to switch out the battery. Sometimes I feel like I am all thumbs. It took a couple of attempts to pull it all together.
I was still getting a low memory message and ended up deleting all workouts including some of the workouts that I had yet to upload to Garmin Connect. Eerrrr
Of course I was upset with that but let it go.
Whatnot am struggling with now that is NoT being let go... Ever since the battery change I have not been able to get the data to upload properly.
Why is it that every time I change out a battery I have a problem with the FR60?
Have to wonder if the more expensive varieties have such issues as well.
