for some reason it wont let me download :( it keeps saying "cannot read property 'build' of undefined"
Update: I managed to download it from the website!! Though, downloading through the app still doesn't work for me as far as I know...
Oh if you're on Mac that's a problem with the way Apple manages apps. This is a third party demo build that can't be verified, and depending on your Mac the device might automatically refuse to let you have it. I'm really sorry. You can try to search for ways around that, but it'd be based on whichever specific Mac you have and I wouldn't be able to help.
