Hy Zack Katz,
First of all - Thank you so much spending time on giving us the opportunity to update posts via GF.
In my case I would have 3 questions:
1. Uploaded images are not visible in single entry view form
2. Cannot update post because the form says "There were errors with the edit you made." . And there are several field it says which I should choose, but they are already chosen.
3. Admin-only Fields are visible for the user who wants to update the post.
Would be happy for an answer from use :) .
