I've had a creative cloud photography account for several years. I just got an iphone and installed lightroom from the adobe app store. Are there only a limited number of free features. Do certain features have to be paid for even though I have a creative cloud account?
You probably just signed in with the wrong ID. The email you used to sign in to this forum shows you have a 20GB Photography plan which includes Lightroom Mobile Premium. Double-check that you used the correct ID to sign in.
