I'm using Survey123 Connect 3.1.126 to publish a survey I would like to work when the field device is not connected to cell or wifi. I created a tile package with arcMap 10.6.1 (create map tile package) to level 16 and put said tpk file in the media directory of the survey. It downloads and works fine when my field device is on wifi, but when it's offline the zoom level is limited. I can only zoom in about half way. This behavior is the same on a Samsung galaxy tabPro 12.2 and also my Pixel 2 phone. The tpk file is on the device, so why would it matter if I'm online or not? It's clearly loading tiles off the device up to a certain point. What might be limiting it? Thanks.
