All participants must approve to the entire bundle. We don’t allow you to change anything about the bundle after you’ve sent the page out for approval because you could change the bundle in a way that would violate the expectations of the people in the bundle who have already approved.
So, if you need to make substantial changes then you will need to create a new bundle and have everyone re-approve it. If the changes are minor then you may contact support and they can see if they can adjust the bundle in a fair way.
That said, though, there are definitely a few minor things we could change to streamline some tools for bundle hosts, but the guiding philosophy regarding bundle edits will remain the same.
Hope that makes sense
