Recently I’ve been having trouble with Apple Watch / Monzo on the contactless Oyster card readers in London (I use London Bridge Moorgate stations every day).
Only about 50% of my swipes are accepted. For the rest, I get an error beep and red light on the reader.
Almost always works if I then double-tap the watch button to reactivate Apple Pay and retry the swipe.
Anyone else having similar issues with Apple Watch / Monzo or other banks?
[I would cross-post this on the Monzo forum but unfortunately I was a victim of their purge of right-of-centre forum members]
