Hey there healthyoptions,
Upon researching your question, we were able to find the steps to Add, use, and share boarding passes, tickets, and other passes in Apple Wallet. This link also includes the steps to quickly access your save cards/passes under the section 'How to use a boarding pass, ticket, or other pass on your iPhone'.
If those are the steps you've already tried, then the next step would be to let Apple Support know what's been tried as they'll be in the best position to assist further: Get Support
Cheers!
