Doesn't Open From Google Drive – iComics Review

Purchased the app when I was using iCloud Drive. I've since moved to Google Drive and now can't open files from there. Its a great looking app, but I've had to go to a free (and pretty decent) app to read my comics. Would love an update (its been a while) that would fix it for the app I paid for.
