How to get back the Premium version after an update
If you’ve lost your Premium Version of Muslim Pro after an update, you just need to click on the “Premium” icon on the dashboard.
Then click on “Restore Previous Purchases” to get back the Premium version for free.
If the above method does not work
please make sure that you are only using one Apple ID, the same one which you have used to make the purchase. You may also contact firstname.lastname@example.org if you need additional support regarding your purchase.
