I am getting a "Mobile version not available" modal that wont go away on its own on desktop. I can trick it by making my browser full screen, refreshing, then resizing it back to a half sized window.
Now I wont even check it out because I didnt get that first impression on my phone. I will just forget it.
Just my 2c
I noticed another possible bug. When trying it out on your website, it reports an "Invalid URL" error.
The detailed text on the modal says: We can only load URLs that pass standard pattern checks.
Edit: even if you click "Request mobile version", the modal is there
