Web viewer App is not working with mobile internet but properly working with WIFI.
What is this?
he is talking about the issue that: He created a web viewer app in which he embedded the https: url of a webpage in (mit app inventor) APP but the app only loads the web url with WIFI connection and does not loads with mobile internet.
Just run a test, working OK here with 4G, could just be a signal strength issue if it is a "heavy" site.
Can you please send screenshots
