Mycelium doesn't offer instructions or a blog post or something on their website to explain how you access your coin balance in their wallet? That's shocking! I just did a search and couldn't find anything on their site at all.
Sounds like Mycelium isn't worth your business. If they can't give you support on how to conduct your business with their product, why do you use their product? Don't let a slick UI fool you into settling for shit service.
