Everyone stop msg for a day?

So I match 5 and started conversation all 5 and for some reason today they all say something like “ text you soon” and I haven’t heard them back for a day which is weird. Is it normal or my game broke?

Did it say they would be offline for awhile at the end of their conversation?

Ah, turn out they all reply 12 hrs later at almost the same time. And it turning out they are doing almost the same thing as today too.
