bug report and mall request

I love Admyt but at this stage I can't give them five stars, which I'd like to do. The reasons (a) they do not cover all the big malls despite numerous attempts to inform them. They seem to be chasing small fry. In particular, please: the back entrance of Rosebank by the garage does not have Admyt, and, Cresta. Cresta is big guys. (b). The app is flaky. It keeps forgetting my login when it updates on the phone, and, it seems to not save my card data so I have to re-enter it every time it can't debit. Annoying. This is on iOS.
