It looks like the Workspace project URL contains a CSP header which restricts non-Adobe domains from framing the page:Would be fantastic if Adobe allowed us to do this.

You are right of course. I meant to say that it's "...around 25% of "Desktop/Laptop Visits" (where Mobile Device Type ≠ Other)". Thanks for catching my mistake.

It's still large for us too. On many of our sites, the "Unknown generic android mobile' still hovers around 10% of All Visits and around 25% of "Desktop/Laptop Visits" (where Mobile Device Type=Other).
