This happend recently with a custom page. I make changes to the page structure in slice machine and push the changes to prismic, they are not relfected. I keep seeing the old page structure in prismic.
Also for some reason if I try to fetch the page (page instance created in prismic) with the client it gives me an error of "No documents were returned" When the document exists.
Yes the repo is linked correctly, the sync stopped working suddenly the same day, I first uploaded a custom page, them I edited the page locally in SM and no matter how many times I modify it and push, the changes are not reflected (SM says that everything is in sync)
For testing the sync I'm adding a field called 'test' to the page 'blog' (uid: 'blog') them I push the changes to remote. I can't see the new field in the repo
