I have an weird issue with my Viber application .
I send a msg to end user and the msg is shown as delivered ,but end user didnt get it at all . When I send msg in Canada everybody is getting the msg but out side of Canada .. msg status is delivered but actually it did not .
Maybe somebody knows what can be an issue ?
Thanks in advance
