Hi and Welcome to the Community!!
Please try this sequence:
1) Remove BOTH AppWorld and the Identity app from your BB
2) Do a Batt-Pull reboot (power on, remove battery, wait, insert battery, wait), even if redundant to the one you did in step 1.
3) Install (on your BB) a fresh copy of AppWorld, during which a fresh copy of the Identity app should also install
4) Do another Batt-Pull reboot
5) See if it now works.
