Thank you, I've been able to unlock charged quarks now...although given there was SA7 to buy and I had upgrades that I had bought after that I'm left wondering if I somehow just missed seeing the upgrade before you updated it. UI kind of looks better, but at the same time kinda unpleasant on a mobile screen. I can't quite put my finger though on what is wrong though...it's possibly that playing it in landscape means there's a lot of scrolling involved and there's not much information visible at any given moment. Again I realise it's not intended for mobile, but as it is playable then I hope feedback is still useful for you?
I'll feed back on if the desktop issue has been resolved later.
