I paid for the app full and it still didn't unlock, help!!
I just paid through App Store to unlock but the mobile app (BTT/FTT SG) still does not show more than 20 questions, what to do?
......
You might have run into the above situation, generally you have purchased the mobile app, and somehow it only allows 20 questions.
Here are the instructions to resolve / unlock.
step 1. open the app, make sure you are at the home screen (as shown below)
step 2. tab the
"Upgrade" button at the top of the screen, it will open
"Purchase to Unlock" page.
step 3. locate and tab
"Restore Purchase on This Device If you Have Paid Before".
if your previous payment was made successfully, Apple will verify that and no duplicate payment will occur,
all questions will be unlocked for your device.
(note : make sure your device can access internet during these operations, as this verification need to connect to Apple's server and check your previous payment transaction record based on your Apple Id).
Once a purchase is restored for your device, the
"Upgrade" button will be removed from the home screen, and you will be able to access all the questions.
