I truly hope you're right, and this is all a big system oddity or whatever. But I'm fairly sure the shows haven't had an "available until" date associated with them (like you are saying for The Ark), on the service itself, until now.
I guess we'll have to wait and see.
Do they typically issue a press release for shows that are leaving the service? (Not being sarcastic, genuinely asking. I don't often pay attention to that kind of thing.)
I just checked Crave myself and yeah it really looks like Star Trek is leaving the service. I always kinda expected it to happen eventually once Paramount+ came to Canada, but now, with Prodigy S2 still to come, it makes it unfortunately ominous. The only reason I had Crave was to watch Star Trek.
