No specialty dining reservations available months before cruise date?

[Phantom_Celery]

First time on Viking. Is it common for reservations for Manfredis’s and Chef’s Table to be completely booked for all nights all times months before the cruise starts? Currently all options are greyed out even though reservations are allegedly open for my cabin class (and received a notification). Does this mean because I waited a couple days after they opened until I had time to log in that I simply won’t be able to reserve at all (and will miss out), or is there some trick / onboard way to do it?

 Thanks!

Sorry don’t know how this got duplicated!
