already tried to uninstall, sign out of my itunes session and apple store and then try to restore purchase, but nothing works, the account that I am commenting here in the forum is the same as I bought the premium features.
You will need to contact support through Apple to restore your purchase. When you purchase the premium upgrade for Lightroom through the App Store, you are purchasing it from Apple not Adobe. This is one of the reasons I recommend purchasing an Adobe Creative Cloud subscription instead. When you purchase a CC subscription you get Lightroom CC for a computer, as well as Lightroom CC Premium for your mobile devices. I think it’s a much better deal. You may want to cancel the App Store purchase and then sign up for a CC subscription here Creative Cloud pricing and membership plans | Adobe Creative Cloud All of the Photography Plans include Lightroom Mobile premium features and Lightroom CC for your computer.
