My error:
I've seen this error be addressed in the past, and I've followed solutions that were provided in those places, including the one that seemed to work the most: http://reactor.apppresser.com/blog/io...
However, I cannot seem to fix this issue. I have remade my certificates, App IDs, push certificates, ensured that everything was up to date and that I was using production certificates all to no avail. Is there any other issue that might be going on that I might have missed?
