MY Zoom invitee was instructed to update his Zoom App and then start paying

[SkipM]

I sent a zoom invite to someone that I have zoomed with before and when he went to open the link , he  received a message from zoom  that said

“ you are required to update the application" and they offered him  a free month ?  he has not  been using  an paid account of his own.

 why would he receive this now  if  he is logging onto my zoom invite I sent him ?
