They are supposed to be connected, which is the reason they make copies of your passport at the second test. Whether or not that worked all that well... I manually uploaded mine and it went to low risk, after waiting 24 hours from the time of the result being emailed to me. I stopped getting notifications in the app afterwards. If it would have changed by itself eventually, not sure, but I was eager to upload the result in order to delete that useless app from my phone.
