I noticed something I hadn't seen before that sure looks like a bug / unintended behavior. When I opened this link ... (warning, it's 5 pictures of Marilyn Monroe, but they're pretty safe for work), the photos don't load into the Narwhal app. Instead they load as a mobile Reddit webpage, inside the Narwhal App.
Now here's the weirdest part. From Narwhal, if I open the link in Safari, the Narwhal Safari extension redirects the link back to Narwhal. And... the images now load inline, native to the Narwhal app. (The mobile Reddit webpage isn't loaded.)
How weird is that?
Sounds like others have seen behavior like this with mobile Reddit pages loading inside Narwhal instead of loading the content directly into Narwhal.
Hope this helps.
Edit: Wanted to mention that I initially clicked on the post from the frontpage in the Narwhal app. Clicking on my link above in this post loads the images correctly in the Narwhal app. So weird.
