FWIW it's worth a lot of the anomalies I was seeing yesterday have been resolved overnight: the missing flights from YYC & PVG have appeared, as have the schedules for BNA & MSY. Nothing for SJC so far. MLE is back on the winter timetable.
I would imagine it's the last over-running decisions on resource planning that are being resolved.
Which makes it strange that the OP's SEY flight hasn't also appeared. Maybe they are still finalising decisions, or maybe they do have other plans for the 787???
Might be a good idea to sign up to baredemptionfinder.com's premium service: a few quid for a couple of months of hourly alerts as this could change any time really.
