Offered on app 2 location codes each 5 figures with only last digit in each different (a1&2)-from car looked at sign and chose wring one so paid for 3 hours at parking where I wasn’t parked(fullwell not Fairlop -Redbridge places.Got £30 fine which I appealed and lost.My beef why didn’t ring go not give me just my actual position and why not if there are 2 possibilities have more figures to differentiate position and aid spotting the one to choose .Make signage a help to choosing position not a contributory factor for confusion.Presumably your computing power is not up to this??
