not pulled anymore since month on tag based build

I noticed that since a few month docker hub does not pull the anymore if I update the repo with a new tag (and new info in the everything works, but the on docker hub stays the same. I have to manually update it by hand. Is this a known issue? Am I doing something wrong? When I add a new tag, I update the main repo too via github. I do not have branch builds, only tag based ones. Might that the be problem?

I haven’t heard of it, but you can find known issues in the Issues · docker/hub-feedback · GitHub repository on GitHub.

I don’t know if it is an intentional change or not, but to be honest, I would like to see a feature (I haven’t asked for it yet) that makes the README sync optional at least. I have multiple branches in a single repo and I have to generate those repos from the main branch just to have common README so it stays the same even if I change the main readme.

Tag itself would not change. You mean you add some new content, change the readme and after that you add the tag? It should work without builds based on branches, although I always use branches so I know when I add the tag, the release is already tested and have a built image on Docker Hub so next time It’s just retagging the existing image and pushing the tag.
