My WAB version 2.12 will not see my published map services when accessing through the web application developer edition 2.12, however, the web apps on our arcGIS Server do show the map services. If I use a previous version of WAB, 2.11 then I do not get the error map services not found. I deleted my signin.json, re added my appid etc still did not help. Before I remove wab 2.12 is there an easy fix to this as i do not want to re-import all my apps and re-customize them.
