I have built a a tile cache using the Manage Tile Cache tool in ArcMap 10.3.1. I use RECREATE_ALL_TILES as the Manage Mode and ARCGISONLINE_SCHEME as the Input Tiling Scheme. I create only the top 6 levels and I use an area of interest for a small area. I then use the Export Tile Cache tool to create a tpk file but when I try to use this in Survey 123 it doesn't show up. It seems like the only way a tpk file works is if I create it using the share as option and create a tile package. But this doesn't allow me to to use an area of interest which results in a huge file that draws so slow you couldn't use it! Can anyone offer any suggestions? I will eventually have to use all 20 levels so the tpk will be even larger and slower.
