If you are using the booking.com pulse app, you can no longer receive the security code number with your phone sms system since the new update . Cannot find the issue,checked all the settings but everything seems to be the same as before. Does anyone have the same problem with the app?
Do you received codes (OTP) from other apps ? If not then might as well contact your carrier and check with them if Short Codes is enabled on their end if so have them disable it .
