Why hasn't my student received their SMS invite? SMS invites created after 9pm UK time will be sent the following morning. Have more questions? Submit a request 1 Comments Date Votes 0 David September 15, 2019 19:38 Sent a couple of invites at 8:30pm (ish), well before the 9:00pm cut off, but had the message "as its a bit late, we'll send a text tomorrow at 9:00" message displayed on both of them. Why is this? Please sign in to leave a comment.
