My pass didn't change on people's phones

Your pass has its own words. Changing your card, or publishing your card, does not change the pass.

1. Open Wallet and make your change in the pass editor.

2. Press Publish this pass. Saving alone keeps the change for you: the answer says "The phones already holding your pass still have the last published one".

3. Read the answer. "Published — phones are being told now." means the phones were told just now, and it lands in a few seconds.

Still the old pass on a phone?

• A phone that is off, or has no internet, picks the change up the next time it checks for the pass.
• The person may have removed the pass. Removing it stops every change reaching them.
• On an iPhone, the pass's own details page has a switch for automatic updates. If they turned it off, their pass does not change by itself.
• A place you save or remove goes out at once only while Instant Push Broadcast is on, under How changes reach the phones. Switched off, each phone picks it up the next time it asks for the pass.
