Emergency Kit Can't be opened in Chrome/Firefox for iOS

Hello,

I freshly registered for 1password and just logged in from the webpage for the first time using Chrome for IOS. I was prompted to generate my Account Emergency Kit.

But trying to open it just resulted in Chrome opening a new, blank tab with "about:blank" in the address bar.

Maybe chrome mobile can't handle "blob:" URLs?

Copying the URL from the "Open PDF"-Button of the PopUp but leaving out the "blob:" such that
blob:https://my.1password.com/$HASH
becomes
https://my.1password.com/$HASH
Does not solve the issue. I'm getting redirected to the login page. After filling out The account information I'm seeing the standard web interface again but no PDF.

Hope this problem can be solved.

Last but not least some technical details:

• Browser

  • Chrome Mobile for iOS
  • Version: 52.0.2743.84

• Name: iPad Air (WiFi + Cellular)

• Identifier: iPad4,2
• Model number: A1475
• Model: ME987FD/A
• Platform: s5l8960x
• BoardConfig: j72ap
• BDID: 18
• CPID: 35168

Thanks in advance for any tips and
Kind regards,
JJ

EDIT:
Similar behavior goes with FireFox Mobile for iOS, but on clicking the "open PDF" button the PopUp just closes (no new tab opened). Copying the URL manually doesn't give any success either.

• Browser
  • FireFox Mobile for iOS
  • Version: 5.0 (2)

EDIT2:
With Safari on iOS everything is working as expected and the PDF is showing
