Sorry last message from me I promise!!!

if you installed the app when it showed paid, uninstall it and redownload, wait a 1-2 hours and try opening it again!!

Terribly sorry for the confusion, come on testers you know what to do!!

Uninstall, reinstall the NEW free app and test please!

Thanks so much everyone!!
