Tap to Pay not working for Apple Pay on my iPhone

Hi. For the past couple of days I’ve had an issue with using my contactless Apple Pay feature. However, double clicking to complete online purchases remains functional and when I use my actual physical card for contactless in stores, it works fine. So the issue isn’t with my card or the in-store card readers, it’s an Apple Pay issue. Anything I can do to resolve this? Thankyou.
