HULU not allowing login on Apple TV4
I have a HULU subscription which I bought directly on the Apple TV from iTunes. After installing tvOS 9.2 the HULU fatally crashed and I had to reinstall it. When login in I am choosing the 'bought on iTunes' option but I receive an error messages telling me that in-app purchases are not allowed.
How can I recover my HULU account? Since I haven't purchased the subscription via HULU I don't have a dedicated login and password for HULU.
Thanks,
Oliver
