override not working for specific user

I have a visualforce page like this:

<page>standardController="Patient __c"

extensions=“skuid.Redirects”
action=“{!redirect}&objectType=Patient__ c&actionType=View”>

And Page Assignments like this:

I have one user who is not getting redirected correctly. She is getting the standard salesforce layout, with this URL:

https://thecenterukiah.my.salesforce.com/XXXXXXXXXXXXXXXXXX?nooverride=1&sfdc.override=1
The user:

• Has a skuid license.
• Has the skuid page viewer permissionset
• Has access to the page through sharing rules
• Has permission to read and write the object in SFDC

What am I missing?
