Hello! You could try doing short videos to bring attention to your channel. They're easy to make you one, record a vertical video from your phone (4:3), record one and crop/resize to fit the vertical fornat, etc. It also has to be under 60 seconds for it to show and a great way to bring attention to your channel if done correctly and most likely often. You could record a short, vertical video of you doing a KPOP dance!

Thank you so much! It could even help us to upload videos more frequently, I love the idea. So grateful! ♥
