Of course it's buggy and has glitches. First rule of software: No matter how well you design something or how thoroughly you test it, there are always going to be glitches that you missed. It's an immutable rule of coding. They were building a website that had to handle (potentially) millions of hits and the specs were given by politicians (who generally know little about tech).
There were always going to be problems. Frankly, we're lucky that the whole thing didn't just collapse on the first day. But bugs can and will be fixed. It just takes a little patience.
