This issue should be tested in one Android and one iOS device. Test default behaviour Test that LTI woks as it used to by default: it's opened in InAppBrowser. Test disabling InAppBrowser Modify the Moodle database to include disabling InAppBrowser in the app: config_plugins - tool_mobile - disabledfeatures. The value must be: CoreCourseModuleDelegate_AddonModLti:openInAppBrowser Purge all caches In Moodle as teacher/admin, create an LTI with automatic activity completion. The completion criteria should be "Student must view this activity to complete it". In the app, open the section with the LTI. Check that the activity isn't marked as completed. Click the link button at the right of the LTI activity. Check that the LTI tool is opened in the external browser (if your site doesn't support auto-login or you already did it in another device you'll have to enter the Moodle credentials). Go back to the app. Check that the section view is automatically refreshed and the activity is marked as completed. Enter the activity and click the "Launch the activity" button. Check that the LTI tool is opened in the external browser.
