Huh. I don't know what that's all about, but I've heard stories of their dev team not doing any more updates for a while now. It's too bad if it's true, because I think Mycelium is one of the best Android wallets I've ever used. The only thing I ever hated about it was their fee tiers and the user's inability to set them exactly. Oh well.
I'm not sure there's much more you can really do to get heir attention.
Doubtful. Like I said, my understanding is that the developers pretty much abandoned it. I don't know if that's actually the case, but I'd bet it is.
