Just switched from V7 to Vnext Business account on website builder and can't seem to figure out how to upload files to my site. All I see is the option to upload pictures. Need to link to a file that site users can download. Was very easy to do this in V7...

I just got off the phone with tech support. You CAN NOT do this is vnext. In 7 you could (as shown in the video Adrian8 provided, but not vnext. This makes absolutely no sense to me, and I'm at a total loss. 😞
