Hi, does anyone know why the option for 'unsend' or delete for everyone only comes up on certain people . I googled it but it was of no help . It says you can only delete for 10 minutes after sending but that can't be right . I've just had the delete for everyone come up on old messages & it's worked . I've just tried to delete a new message , as an experiment &I only got the 'delete for you ' option .
Thank you
