There didn't appear to be any piers ide testing in Edinburgh yesterday. I had to leave home on Wednesday instead of Thursday because of the train strike, so instead of doing my 3rd party verified antigen test at home with fast internet, I was reliant on a very indifferent wifi at a hotel. Thank goodness I had a backup test. The one I'd booked on zoom failed as the connection dropped out and the observer terminated the meeting. The other was much simpler as I had already registered on the app scanned in my passport etc. All I had to do was input the test order number, do it and upload a snapshot, wait for the 15 minute timer to end and scan the result. I got a message saying please wait 2 to 3 hours for your results, but my phone pinged after 10 minutes with a negative result and attached fit to travel certificate. I downloaded this in case of no signal at the terminal. Everything else I had printed out.
The whole thing took 5 minutes, temperature check, receipt of medical questionnaire, and endorsement by staff of proof of vaccination and sight of verified negative test and certificate.
