Ran into this too, I cancelled the old submission and started fresh, but even then the subscriptions kept throwing "There are errors with one or more of your items. To fix them, you need to remove the items and add them again to your submission" when I tried adding them to the draft. Which is what everyone above has been experiencing as well. What worked for me: Removed all 4 subscriptions from the draft (not just cancelled the submission, removed them as items). I went into each subscription individually and made a trivial edit (removed the . at the end of the last sentence) and saved it. This seems to clear a stuck error/rejection flag that doesn't reset on its own even after a prior submission is cancelled. Re-added each subscription to the draft one at a time. Then explicitly added the Subscription Group itself as its own item too; it doesn't get pulled in automatically just because its subscriptions are in the draft. Ended up with 6 items in the draft: 1 app version + 1 subscription group + 4 subscriptions. Once all 6 were present, "Submit for Review" activated and went through clean, now sitting in "Waiting for Review." So the combination that mattered: edit-to-clear-the-stuck-flag on each subscription (credit to the earlier post in this thread, that part alone didn't do it for me until I also added the group as its own explicit item), plus treating the group as a required 6th item, not just a container. Hope this saves someone the same afternoon it cost me.
