That's great, but this still doesn't change the fact that you've purchased something that doesn't release until June 23rd. I'm curious what your service account looks like on MogStation, specifically the area I placed a red box around. If you have the PS4 bubble there, then something could be amiss, but again, you've purchased a bundle that hasn't released yet, so it's likely to be expected.
Letting you download ARR's client could simply be a means of mitigating server load on release day, and isn't necessarily proof that you're supposed to get half of an unreleased bundle upon pre-purchase.
Edit: Heck, you can download the client for free without having purchased anything at all, so it's hardly an indicator that you're supposed to have access.
