Problems: 1. It auto scrolls for you on videos and reels. 2. You can't save reels to specific collections easily. 3. On stories, if a video gets split into 2 videos, you need to re-place your text and/or stickers into the 2nd half of the video, which isn't ideal if you want it to look seamless. Like with the music sticker, you wouldn't be able to have the music keep playing from one slide to the next. Also this is just a suggestion but instagram should have games in the chat!
