App was pretty easy to set up and useful to use if I didn't have my purse with me. I hate taking just my card in pocket so this was really useful for buying the odd thing. Then suddenly a couple of weeks ago it just stopped working. There is no error message it just literally won't work. It's actually been embarrassing, twice I've had to leave things at the till!?! Tested it again today, checked all my settings etc, still didn't work. Completely pointless and don't trust it now so will delete!
