I also could not connect to the Bluetooth! I have a new Samsung s21 with NO issues! Restarted my phone, uninstalled and reinstalled app. Still no connection! Also felt the extreme frustration of having to refill the entire form and listen to the full video multiple times! You should fill in form once and it's saved. Total waste of time and money. Still sick and now have to run out for another test! I am beyond frustrated!
