The new gear tracker feature is great. I have 3 pairs of running shoes that I rotate through, so I don't have any set as default. I noticed that once an activity is uploaded to GC and I try to choose which of the 3 shoes I used directly from the dashboard, I get this disappointing "Sorry, we were unable to process your request. Please try again." This also happens if a shoe is selected but I try to change to a different one. The only way to assign gear is to expand the activity, then select gear. Anyone else having this problem?
Another bug/feature is that it is currently possible to assign two different pairs of shoes to one activity. I don't know anyone who starts a run with one pair of shoes then switches mid-run. While this is not a big deal (just select one shoe, deselect the other), Garmin Connect should probably automatically deselect one shoe when another is selected. Other tracking websites do this and I believe it's a simple algorithm modification. This auto-deselect would be especially useful if the "default" shoe is assigned to an activity but someone wants to change the assignment.
