I logged the bug with Apple back in Dec 2021 (Bug report no. : FB9813388) and it's still open with zero response from their side. I had a same issues as you guys and ended up dropping the relevantDate and using push updates to get round it, which is ridiculous. That didn't move the passes back to unexpired state, so had some very awkward conversations with very annoyed customers where I had to instruct them on how they can manually move them out of expired state. I haven't tested it since, so have no idea if its been fixed. Anyone know?
