Is anyone experiencing any charging issues? I put the watch on the stock charger when going to bed, the charging screen comes on, but when I pick it up in the morning it is either the same as it was before I charged it, or it dies as soon as I pick it up. Really frustrating that it looks as if it is charging, but it really isn't. First few times I thought I was user error, but now that this has happened 5 or more times, but not every time, I think its the watch or charger.
