Solidworks 3DExperience - xDesign reliability

Hi,

       I have solidwords 3DExperience makers licence. This includes the downloadable Solidworks program, which works fine. I have tried several times to explore the xDesign web based app, as this appears to be the 'future', but many times I've experienced 'hanging sessions', lost connections, non-working functionality - in general a very buggy experience. 

What's the general opinion regarding xDesign - is it as buggy as I'm finding it ?
