I agree with Cricktor, it's probably an intentional move to force people to use only the iCoin. It wouldn't be the first time a company tried to force their customers to rely on only their product.
...so I asked their support team a few questions:
Those questions might be above their paygrade I am afraid. You might get a response like: of course it's open. You enter PIN, wallet is OPEN. No PIN - wallet is CLOSED. 100%. Turn on flashlight for easier PIN entry. 
Lol, maybe so. It is telling that they have yet to respond to my questions. If I ever to get a response I'll post it here.
If I may switch gears for a bit; any body hear about Ledger seeking more funding? According to a couple of articles that came out yesterday, they're in talks with investment firms looking for $100 million.
