Passbook Passes expiring after a day

Question

Generating a passbook file using passkit4j with relevance date of today and no expiration date. However, the pass in apple wallet seems to expire after a day.

Question:

1. How can I make pass with no expiration date
2. What is relevance date ?

Tried changing expiration date to multiple different values but doesnt seem to work

Answer 1

Not sure if this helps, but according to Apple's documents, Relevance Date has no meaning for store cards.

https://developer.apple.com/library/archive/documentation/UserExperience/Conceptual/PassKit_PG/Creating.html

Check Table 4-2

Answer 2

I read somewhere that some versions of iOS uses the relevantDate as expiration date for a pass.

Otherwise use the expirationDate property
