The checks, in order
The share dialog reports the first failure. Fix that one and try again. You do not have to guess which rule fired.
| Check | Pass it by |
|---|---|
| Cover | Generate or upload a cover |
| Published chapter | Publish one chapter whose panels all have images |
| Image count | More than three panel images on a published chapter |
| Review | Wait if the share action says images are under review |
What the link allows
A share lets someone read the comic you chose to expose. It does not hand them the studio. The share and explore feature is the longer version of that rule: drafts stay off Explore until you put them there.
Unpublishing the only completed chapter removes the “has a published chapter” pass. The cover can stay. The share will fail until a chapter is published again.
