Day 2 lateral flow test arrived ok and testing simple to carry out but trying to get the qr code to work and then upload the photo of the negative test is impossible. Called Boots customer service and was told to email them the photo which clearly shows a negative test result. Later received a message that the test was inconclusive. Unbelievable. This was very clearly a negative result. £21 paid for a very poor service. Use someone else to do your tests.
