I have a Sony Xperia z5 compact and have just updated my mobile's software to nougat 7.0. It now has some new and useful features but a major one that I use is gone, or at least, hidden: the groups in the contacts menu. The groups exist, I know that because when I create or edit a contact I have the option to add them to an existing group or add them to a new one. The problem is that when I access the contacts menu there is no way I can choose to use a group to send a text message to many contacts at once. And this is a big problem for me because my work is supported by this feature, big time! Can someone help me, please? I really appreciate it!
