late EACA/QDIA notice consequences?

Getting word that a plan I've been chasing is going to come with us.  Sounds like they haven't yet gotten their safe harbor or EACA or QDIA notices from their current TPA or RK yet for 1/1/23.  It's a SHNEC, so we can pass on that if we have to, fine.  I'm getting information rapidly, but what if we just can't get enough to produce the EACA or QDIA notices by 12/1/22?  I don't see any kind of remedy, like "hand it out as soon as possible" anywhere.  What kind of pickle are they in?  Thanks.
