We have now resolved the below issue:
If you sign in with Microsoft or Google, you will be returned to the Printix Sign in page, but now with the buttons are dimmed. If your account is registered with more than one Printix Home, you will be taken to Pick a Printix Home page, but nothing happens when you click any of the buttons.
The web app is working as expected, and will take you to your list of pending documents after you sign in.
Thank you for your patience.
The Printix Team
