Product Views block is not visible
I've created a view to display a list of products in a block. It's using two relationships and two contextual filters and it displays fine when I enter the necessary URL parameters in the preview bar.
I've enabled the block to display on all pages (for testing purposes) but I can't get it to appear anywhere - even for the user 1 account. Is there some trick to block views that I'm missing?
Thanks in advance!
