User Guide Leads to Web Browser & Not Displaying (Hubspot)

What I was trying to do:

Visit the user guide from Hubspot directly from within the app

What I expected to happen:

Get to the new Hubspot user guide in french (as my phone is french), or english if my phone was english, in an in-app iframe browser.

What actually happened:

1. I was redirected to a Hubspot website in my browser

2. I was able to get to the help, after clicking 'Back to to Resident' from the browser in iphone

The normal behavior was to get the the screen above, but without having to open the phone's browser first.
