How do I send a post/meme to my groupchat on instagram?

I'm the only one in our group that hasn't sent a post but I'm too nervous to ask how. I have an iPhone and a Samsung if that helps. Some of my friends just scroll on a post and click a bubble and it sends to our group but I don't know how to do that either.

  • Why isn't my groupchat working? I have an iPhone 7 and I have a groupchat with 2 of my friends, of which one of them have an Android. It usually takes a while for me to send pics, but yesterday I all together stopped receiving texts from the groupchat. (They texted me while right next to me). I tried shutting off my phone multiple times and I still don't get the texts. But, both friends individually texted me and I got them. What is wrong with my phone?

  • If I post a video on vine with my sound off will it post with no sound? I just recorded a video for vine. After I made it I noticed my switch was on silent. (I have an iPhone 4S) so I turned it on and the video still had no sound. I checked all my settings and everything was on. All the other videos on vine had sound. So I posted it hoping maybe when it posted the sound would come on. Still no sound after it posted. Is this because I had the switch off when I was recording?
