Thank you, @Gtinnel!I’m still new but I can try to help.
Find the ad posted by SBB and click on the symbol that looks like a paper airplane
Then click add post to your story
You can use the buttons in the top right corner to add words, stickers, and effects. Then when done click the arrow in the bottom right corner
Make sure the circle beside “Your Story” is highlighted then click on share
Then select done and you’ve added it to your story
To be able to see your story to screen shot it just go into your IG and click on the profile pic and it will show your story
This is at least how to do it on my iPhone. Android or PC may be slightly different but it should be similar.
I’m still new to this also, so if anyone sees something that I’ve said wrong please feel free to correct me.
