Pages 5.3.3 Update
I have downloaded Pages 5.5.3 from the App Store and upgraded to OS X Yosemite (10.10.3), but for some reason when I open Pages I'm still getting the older version, 5.2.2. I'm trying to open a document that's been emailed to me, but Pages gives me this message:
"You need newer versions of OS X and Pages to open this document. Install the latest version of OS X, then download the latest version of Pages from the Mac App Store."
When I click OK and zip over to the App Store, it tells me that I'm completely updated. Any ideas?
