I was trying to cancel my subscription before the free trial ran out because I did not need the service beyond that. I attempted to do so by going in to my subscriptions manager on my iPhone but Adobe was not listed. I could not cancel what I could not see, but I was charged anyway. I'm not even asking for a refund but I would like to prevent any further charges and cancel my subscription
