Issue with arab region format in Pin Master
Some users in the Arab world are experiencing a crash when adding a pin. We apologize for this inconvenience. The issue has been resolved and the update has been submitted to the App Store for review by Apple.
In the meantime, you can bypass this problem by changing your iPhone Region Format to a different value
To do this, go to
iPhone Settings > General > International > Region Format
and select United Kingdom
After you download the updated version of Pin Master, ofcourse you can return to your normal region format.
