Very hit and miss implementation of payment verification for online purchases. Sometimes takes 3/4/5 attempts to go through the process of verifying the purchase with the app throwing errors at random. Notifications won't trigger unless the app is open in the background either. So I have to open and then go to my home screen before clicking purchase. Have deleted/reinstalled to no avail. My credit union and revolut verifications are flawless so it's not the device/fingerprint reader.
