Saints Testimony on iBooks UK

So I pre-ordered Saint’s Testimony on iBooks in the UK bookstore. But it wont let me download it, and I can’t find it anywhere in the iBook store. I think it’s a UK problem as I’ve seen a few other people on the net having the same problem in the UK, but it could be elsewhere as well.

Don’t know if 343i reads this forum often, but can this issue please be addressed? I’d rather like to get the book that I purchased. Thanks!

Have you tried reaching out to iBooks support? That will probably be the best place to start
