I am also having horrible issues with group texting. I have a group text with 4 other people. Doesn't matter if it's iPhone users or Android users I am texting with. Sometimes when I send a text in the group, 3 of the users will get it in the group conversation but 1 of them will get it as an individual text. The next time I text, all 4 get it in the group. Seems my text is always received one way or another but lots of people are telling me that the text I just sent came up as an individual text to them when I responded to the group text. The others in the group do not see my text. This is with any group. Separate group, different people, same thing. I have erased all my text strings to start fresh but didn't improve. I am using the Messages app on my Samsung Note 10. Not sure what the issue is but it is VERY FRUSTRATING
