In order to allow field workers to access interactive maps in the field, I created some web apps in AGOL and installed the latest ArcGIS Explorer app on their android tablets. Everyone has their own viewer account and things have been working great. However, in the last few weeks some of the workers have been experiencing problems with random layers in the web maps not displaying. The fix for this situation seems to be logging out of the app/AGOL and back in again. This procedure is very annoying to our workers and didn't have to be done in the past (they logged in once and stayed logged in unless the tablet shut down). I am wondering if the new security updates ESRI put in place are messing with things. Anybody else having this issue?
