While I absolutely love your product, I'm afraid we're not going to be renewing the subscription to your service.
This is not a failing on your part, but more the absolute pain in the @$$ that the whole 'app review' process that FB has implemented, coupled with the weirdness that Twitter is mucking about with (been getting intermittent 'bad request' errors for months).
I understand that FB got ganked by Russia, and that's too bad, but they've made the whole process so draconian and esoteric that you need multiple bloody PhDs in Astrophysics, Quantum Mechanics and Underwater Basket Weaving to even begin to understand the damn questions they're asking.
I'm sorry for the rant, I know it's not your fault, but after ranting at the blank wall that is Farcebook, needed to vent.
If they ever pull their collective heads out of their backsides, then maybe we'll revisit the issue.
But for now, it's adios for us unfortunately.
