Iphone user, this is what I did. — I deleted my ST that had moved into “expired passes” in my Apple wallet after the Brighton game. Step 2- went into Everton FC App / Logged in / Tickets / pressed “season ticket” (that was in a tile top right of the screen) another bigger ST tile comes up with the EFC crest, pressed “add to Apple Wallet” ……resolved….. not yet…. Went into Apple wallet, ST was back in there, but had not updated to show “Mansfield town”. Pressed the circle with three dots in the top right (apparently called an ellipsis icon), pressed that you get a drop down list with “notifications”, pressed that and you get three toggle switches, top one being “Automatic updates” flipped them all off and back on again…. Hey presto ST updated in wallet to say “Mansfield Town”
Hope that may be of some use to any Iphone users still trying to get it sorted.
