I think the views on the Shorts you post are still consistent, right? I mean, you still have videos hitting the trending page. Even though one video got hit with the Shorts policy restriction on June 29, your June 31 video still reached nearly 30k views. That shows your channel is still fine. I think it’s more about the content or just luck, the kind of video YouTube decides to push will naturally get higher views. That’s just the nature of Shorts.
If you’re worried about shadowbanning, you can use some tools to check, but only as a reference. If you have multiple channels, you should separate them by logging in and running them on an antidetect browser like Multilogin, Hidemyacc, or whatever you prefer, each with its own proxy. At least this way, your setup won’t be the cause of a shadowban. But in your case, since you only have one channel, I’d say just keep making videos.
