I've been trying all morning to take an Arcgis Online map offline for use in Collector. I've simplified the map way down to just the standard Topo vector basemap and a couple of hosted feature layers for a small area. No matter what I try the download goes slowly for the first third or so of the progress ring, then just hangs there. I was supposed to be out in the field with this several hours ago. I'm trying to download a small area, only about 20 acres, and I've tried various detail settings.
I finally had one attempt appear to finish, but then the map area wouldn't open, and if I hit "sync" it would fail.
Any tips on getting working- this has worked fine in the past.
