IOS26 NFC/Express Transit randomly fails for London TFL Tube
Arrived in London four days ago, and the iPhone tap for the London TFL Tube randomly fails. Sometimes you have to double-click for card authentication, but that does not always work. You have to walk away and then try other exit or entry readers. This is an issue with all 4 iPhone users in our family. We all have the latest iOS 26.0.1. We have an iPhone 15, 16, and two 17s. They all randomly fail at the turnstiles. The credit card selected for Express Transit Card is the Apple Card on all 4 iPhones.
Apple Pay functions as expected at payment terminals with no issue.
This appears to be an issue with iOS 26 because a couple of months ago there were no issues in London with iOS 18.
