Send text message to group

[Windows Central Question]

I have Windows 10 mobile Build 10586.107 in my Lumia 720. While sending text message to group the + sign shows only individual contacts and do not shows the groups or its names.

Further, while sending text message within the group, it shows only three members instated of all members so removal of any member or editing the list of recipients is also not possible at the time sending.

Please guide how to overcome the issue ?

has still no idea why group messaging isn't shown on 950. Have set a group up in the contacts (group has 96 members), but no option to send a group SMS.
