We have developed our own app, and we got a problem the images are not loading, it does load in the Moodle Default app, however, in our customized app it doesn't load.
When the user logins for the first time, it does load the image, but after the user reloads the page or gets back to any page, the images are gone.
The only way to get it back is by going to settings --> Space usage --> Delete site files.
Is there any particular reason for it?
Check the images attached.
