Where did my comics go?

A lot of my comics have disappeared from the app. Most are still in my library on their site, but even some of those are gone. When I show my collection side by side, on the website and in the app, there 14 on the site that dont even show up in the app. Seriously? Dont even make an app if youre going to screw up peoples purchased content.
