Help, Anyone?

Hi, Wondering if anyone can help.

I tried installing the latest beta plugin and have the following error.

Fatal error: Call to undefined function displayAppStore() in /home/content/33/9857133/html/funformobile/wp-content/plugins/app-store-assistant/includes/app-store-functions.php on line 832

I am using wp theme “my-mobile-page-v3”

Regards,

Kay
