Thanks wilkins.eth — good to know things are working in those places on your end.
I should’ve been more specific: The Rainbow app recently has an in-app browser, and I’m seeing the issue in the in-app browser.
I’m able to connect with Rainbow via mobile Safari.
I’m also able to connect with Metamask, but seeing as they appear to throw an error message for artworks that include iframes, and then don’t display the artwork, I can’t recommend it to collectors.
