With the new interface sharing feature in the beta, people can also view with a public URL without logging in. 

You can use a formula field for this task, but ARRAYJOIN alone will not be sufficient. The formula below will give you what you want, but it won't be an efficient solution:MID({Orders}, 1, FIND(",", {Orders}) - 1) & MID({Sizes}, 1, FIND(",", {Sizes})...

I had the same problem. "Share View" button isn't visible in my pro plan. You could prefer to create a list view in interfaces, then you could share by e-mail or invite link.
