I have updated a bundle I have made to include new items. However, I've received a message from someone who purchased the bundle a while ago saying that they can't access the new content (it's acting as though they don't own it, when they should, since they own the bundle and the new content is now included in the bundle) and furthermore, it's also acting as though they don't own the bundle anymore (when they got to the bundle page, it shows the "Buy all" button instead of the "access content" button or whatever). Is this how bundles are supposed to act? That seems less than ideal if so. How can I give existing users new content if this is the case? I'm kinda worried that I'm going to have to send out new keys to every individual existing buyer whenever I update the bundle to add more content...
