I have the following problem: In the Moodle application there is a personalized screen to access some courses, for this a "mustache" file was added to the Moodle code with the following code: <ion-list > <%#Cursos%> <%#.%> <ion-card style="height: 50%;"> <img alt="Silhouette of mountains" src="<%wwwroot%>/theme/almondb/pix/portada.jpg" /> <ion-card-header> <ion-card-title><%fullname%></ion-card-title> <ion-card-subtitle><%shortname%></ion-card-subtitle> </ion-card-header> <ion-card-content> <ion-list> <a href="moodlemobile://<%wwwroot%>?redirect=/course/view.php?id=<%id%>" data-open-in="app" style="text-decoration: none;"> <ion-item lines="inset" detail="true"> <ion-label> <%fullname%> </ion-label> </ion-item> </a> </ion-list> </ion-card-content> </ion-card> <%/.%> <%/Cursos%> </ion-list> Custom URLs were used to achieve this. On Android the application works correctly, when you click it takes you to the course screen, however, on IOS it gives an error: "failed to load webpage with error unsupported url" I have tried the following solutions that I found in other forums <meta http-equiv="Content-Security-Policy" content="default-src 'self' data: gap: *; script-src 'self' 'unsafe-inline' 'unsafe-eval' *; style-src 'self' 'unsafe-inline' 'unsafe-eval' *; media-src 'self' 'unsafe-inline' 'unsafe-eval' *; img-src 'self' 'unsafe-inline' 'unsafe-eval' * data:;"> preference name="WKPort" value="8080" preference name="UseScheme" value="false" <allow-navigation href="moodlemobile:*" /> [Image Edited by Moderator to Remove Personal Information]
