It’s come up on the app saying I’ve to isolate for 9 days, but the only time i left the house on the day I’d had to have been in contact was to go to the shop in the evening, it was really quiet and there was hardly anyone in there at all (big supermarket) and I used the self checkout I’m pretty certain I wasn’t within 2 metres of someone for 15 minutes, I don’t think I was even in the shop for 15 minutes.
Can the app be wrong? Would you isolate anyway just in case or not?
