I renewed my subscription on the App Store, but I cannot access as premium functions in the app. I can't renew because I remember and I can't use the restore purchases function because "Duplicate purchase" appears, what do I do? I have an Iphone 6.
Interesting to know if you solved your problem, as I have exact same issue since I got new phone , was able to restore all premium apps except the Lightroom and continue paying but can't access premium features:(
I see no sign of any subscription for the email ID you used to post on the forum here. I see this account was created today, so I wonder if you have an older account that should have the subscription you expect to see.
