SSL Error

The app will not load and has not done for days now - it keeps telling me an SSL error has occurred. I can’t log in through the web site either - the browser cannot establish a secure connection.

This is a mastercard app we’re talking about, not some little game or something, and it doesn’t work, with no explanation and no sign of a fix forthcoming - so for now my Optimum card is basically useless.

Please sort it out.

Horrible Interface

The app has worked alright for me despite been a little sluggish at times. My issue with the app is that I cannot stand the interface. All the fonts and text sizes are totally different than that of the standard iOS interface and whats more it has a dark background which I also find rather annoying. I would like to see an interface thats consistent with iOS interface.... in other words the same font, same text sizes and same white background.

If you need to reinstall it won’t work again.

If you need to reinstall the app it won’t work again. Can’t login again. The continue button on the login screen remains disabled. Developers: please do not reply with a message to say “ring customer support”. You know that will cost me money! Just get on and fix the issue described!!
