Are you having any other problems with any other apps? Is this using data?
I would suggest logging into My EE and clicking on the three lines on the left at the top, if using the app, then settings, then restrictions and see if content lock is switched on, as this would need to be off, hope this helps.
To contact EE customer service dial 150 from your mobile phone or ring customer service for free using web based app or another phone: +44 800 079 8586 or +44 800 956 6000.
