Impossible to cancel Fitness Coach App
I made the mistake of removing the "Ask to Buy" from my son's phone because it stopped pushing approval requests to me. He immediately signed up for the Fitness Coach app, which has a brief trial and then automatically starts charging $4.99 a week. No big deal, I thought, I'll follow the link in the email and cancel the subscription. That is where the problem begins.
I opened the link and even though he's on family sharing I could not access his account on my phone or Mac. I opened the link on his phone and in Manage Subscriptions there is no link to cancel, only to change the terms of an excessively expensive app. I cannot log in to my son's account even with my parental control on Family Sharing. I do not receive the option to manage the subscription on my login, but I worry that I will be liable for the charges even though I cannot cancel.
I'm amazed that the App Store has left this app on the roster, since it appears to be a scam and online reviews of the developer (Luni) underscore this issue.
Anyone have any help for me? I emailed support four days ago and have still not heard back. I emailed again today but thought this might be my only hope.
