Pretty good platform. Not sure if there was a recent upgrade, but it ALWAYS locks up on the mobile application when you switch between functionalities. It's very annoying to have to close out and reopen just to go from a market view to portfolio view. Unfortunately, Coinbase has a non-existent customer service group, so I'm relagated to posting this here with the hope that they will see it. Good application out of the box, but the last three months has gone downhill.
