I created a web map from a published service and shared with a particular group. All the layers show properly. I than created a web app from this web map and shared this as well. All layers in the web app show properly when viewing on desktop. Problem occurs when I scan the QR code and open the shared URL link on smartphone. It takes me to the web app, but none of the layers show. Anyone else have this problem or know whats causing the layers to not show on the mobile/tablets?
If the app has not been deployed (if using WAB Dev Edition) then the QR code will not work. If you are using the AGOL version of WAB or the app has been downloaded and deployed to your web server then the QR code will work fine.
