IA does not appear to be accepting non whole numbers for hiking miles (again). This is when attempting to approve an activity from the pending items tab on the roster section:

I get a Whoops error when I try to approve the same activity from the hike activity log on the scout’s profile page.

The solution has been - enter as a whole number (4), and then go back and edit after submission to make it the proper number (3.3). I know the SUAC team submitted the issue, but there was no ETA on the solution.
It worked! Thanks for the tip @RonaldBlaisdell. Hope they get this fixed soon.
It looks like service hours has the same issue as I am not able to approve service hours unless a whole number.
I haven’t tried the approve a whole number than edit.
Kind of surprised you can track the miles to that accuracy. Pretty much any GPS signal is going to have a bit of variance. Using a pedometer requires a very accurate pace to have sub-mile accuracy. And having made maps, they are all a bit off.
I’d just round them off.
This is the same way with service hours where if a scout gets 1.5 I am not going to round that to 1 or 2. Just logged in to see if maybe its been addressed yet but still no go.
