I have subscribed to the premium version of lightroom from the apple store but in app premium features where not working. I tried paying for both the annual and the monthly plans but neither would work, both these actions were tried from my iPhone and using the same icloud account.
The only thing that worked was logging with my apple icloud from the macbook and paying for the monthly plan. The problem is now I have 3 subscription active and charged in the same icloud account, I need to either have my money back or cancel two of these subscription passing the premium time for only one account what would be over a year access.
I have contacted apple but it seems to be a bug in the app.
I see only one subscription for your account here, a Lightroom 1 TB plan subscribed directly from adobe.com and not through Apple / iTunes services. This account is based on your Apple login, and to use this plan on both desktop and mobile, please be sure you are signed into the same iTunes account on all devices.
If you did subscribe additional Lightroom Mobile plans, they must be using different accounts than what I can see for you. For additional help signing into your correct Lightroom account, please contact Adobe Support directly by clicking here, https://helpx.adobe.com/contact.html?rghtup=autoOpen ...and in the chat field (lower right), type AGENT
Even if Adobe Support can locate your additional Lightroom accounts to help you cancel, you may need to reach out to Apple Support for cancellation and refunds.
