This. When my wife first got an Android phone I installed Signal on there as the default SMS app (she values her privacy and was worried about Google Hangouts). This lasted for almost a day until she tried to send a group text to a few of her friends. When she found out she had to create a named group first, she asked me to install a different messaging app immediately.
