Can anyone help me figure out why I can't see Instagram links embedded in posts on the Cardboard using Chrome on Macbook Pro (OS 10.14.6), but they work fine using Safari on the same computer?  No ad blocking is engaged.

I mainly use Firefox, and it has something called enhanced tracking protection, which is default On, but is customizable by site.
And I found helpful to turn off for Cardboard to be able see everything.
Not sure relevant to your issue but mention just in case.
