Invisible Ink does not work
Hello!
I have an IPhone 5se, with iOS 10.2
I'm trying to send an sms with invisible ink, but the person who is receiving (also an iPhone 5 with iOS 10.2 user) sees the sms as usually, followed by 2 brackets where is written "invisible ink". Also I can't send ballons, confetti.
Where is the problem?
Thanks!
