I recently bought a Playbook (they are on sale everywhere - really cheap!) tried the latest version of ST2.2.1 and it appears the forms don't work.
I tried the navigation view example, forms example and the kitchensink none of the form pages in these applications appear to display.
Wanted to know if anyone has experienced the same issues. This is with the latest Playbook os 2.1 they don't support BB10 on the tablets.
