The camera timer and timed review mode is not currently a feature available on the iPad 2 as we don't have camera support in our application for that device in our current release. I apoligize if feature support was not clear when you purchased this addition.
We review product requests as we make refinements for product releases so please submit your request here.
Thanks again for your feedback.
Photoshop Express version 2.0.2 was released on iTunes App Store yesterday, which adds all current Camera Pack functionality to iPad 2. It should offer itself as an update to your currently installed app.
If you have already paid for the Camera Pack, the features should automatically reveal themselves in your app. If not, go into the Photoshop Express app Settings (gear button at the top), then select Purchases > Restore Purchases
Here's a link to Photoshop Expess for iOS:
The correct link to Photoshop Expess for iOS 2.0.2 (which includes camera support for the iPad 2) can be found here:
Also note that in addition to iPad 2 camera support, users who opt not to purchase the Adobe Camera Pack now have more control over messaging in the app.
