问题
I've tried searching for a solution with no luck yet. I am trying to use the google app invite to invite friends to use my app (android). Emails are sent but sms are not. I do not get any error message, in fact I actually get a message that the invitation has been sent. I also tried adding sms permission to my app.. Any thoughts?

Same problem here. To solve it reduce the length of your message.
As we know, the message must be not longer than 100 symbols. But this is true only for latin characters. If your message contains at least one non-latin symbol (it switches to UCS-2 encoding), then the maximum length becomes only 39 symbols long (have tested Russian only).
So if you're trying to submit 40+ symbols, the message won't be sent.

I had the same problem. Emails were sent, but SMS messages not (although the app showed a snackbar saying that the invitation was sent). Apparently SMS messages are not sent when the message text contains some "more special" characters. In my case the text contained a "ë". After removing this character, SMS messages were successfully sent.
