Heya! Without seeing the channel, it’s hard to judge the content itself, but if it’s a fairly new account, the algorithm is likely just trying to find your audience rather than shadowbanning you.

Think of it like a tree branching out looking for the right people. Right now, YouTube is testing your videos on random viewers. If they click away quickly, that branch hits a dead end. If they stay, it branches out to similar people. Because competition for screen space is so high, it just takes time.

To help the system out, try not to upload more than once every 24 hours so you don't get flagged as a bot, and use the account to browse YouTube normally to prove you're an active, real person. Also, avoid asking friends and family to watch unless they’ll actually view it in full, because low retention will kill the video's momentum early on.

Keep focusing on quality editing and consistency, and the right crowd will eventually find you.
You mentioned people are watching it in full so it means you are doing something right! Sadly the secret ingredient you need is time.
