Getting errors. – Guide for Dragon City Review

When I switch to another page, like from All Dragons to Favourites, it gives me an error. The error reads, “Expected status code in (200-299), got 503.” I’m not sure what this means, as I’m not a genius with code, but an update to fix this would be nice. It seems to be an issue with the images in the app, as they’re always stuck on loading. Otherwise a great app.
