Unable to purchase AR Viewing license - button does nothing!

While using the ios SketchUp viewer app, I’m trying to unlock the AR Viewing license by buying the 9.99 subscription… but the SUBSCRIBE button does nothing! It doesn’t take me to the purchase page.

Is there another way?

Trying it via the app store gives the error CANNOT CONNECT TO ITUNES STORE

Touching the $9.99 in the Subscriptions part of the App Store page for SketchUp Viewer does open the app and asks me for Touch ID to confirm my purchase. I declined, because I already get AR via a SketchUp subscription. But at least the steps seemed to work ok.

Good thing I wasn’t using my iPhone, Face ID might have cost me $9.99 to do that test.
