ComiXology's TMNT comics app

[Icegaze]

I uploaded the TMNT comics app on my iPad (via iTunes) on Monday but I am not able to find IDW's TMNT issues.
I don't have access to the Comics Store (it keeps saying that the site is "temporarily unavailable" since yesterday).

The only issues I can "buy" (because none are free, contrarily from what I read on iTunes saying that 3 issues were free) are:
- TMNT classics vol 1 and 2
- IDW's issue 13 (Karai on cover)
- IDW's microseries April O'neil and Fugatoid

That's all.

I have used the search bar to find out if there were more issues on the app but nada. I'm so disappointed and frustrated.
I don't live in the USA so I cannot buy the paper comics. Digital is my only way to satisfy my need for IDW TMTN action. I really want to read this new series that came out since last year because of the previews I've seen, and the positive reviews and feedbacks I've heard.

Can anyone help out a brother in need?
I've sent an email to IDW requesting for explanations and solutions ASAP.
