You can avoid using Chip and PIN by tapping for your next transaction.
The payment will fail, but you’ll have the option to enter you PIN into the app (open up the failed transaction in your feed). Once you do that, try your payment again (it must be the same amount at the same merchant) and it will succeed. It will also reset the contactless counter so your card will work normally again.
Alternatively consider using Apple Pay or Google Pay. Those options never require Chip and PIN.
