Ok i reinstalled LR on my iPad and made sure im signt in with the correct account. Unfortunatly this didnt work. I still get the screen that i can start my 7 day trial or buy a premium account via the apple appstore.
When i go to my account settings on the website (adobe.com) i get the correct abo:
Creative Cloud (alle Applikationen)
On my PC and my Macbook air i can use LR, LRC, PS and Premierpro without any problems.
The premium features are marked with a blue star in the screenshot i have attached.
