Hi @happy_precision6122,
We reviewed your account and confirmed that the Lightroom Mobile subscription was purchased through Apple/iTunes. Since subscriptions purchased through Apple's billing system are managed directly by Apple, refund requests need to be handled by Apple Support. I can also see that our support team previously shared this information with you.
I can confirm that the subscription has been successfully canceled.
If you have any other questions or need help with anything else, please feel free to let us know. We're always happy to help.
Take care, and thank you for being part of the community.
Thanks,
^Shivangi
