Problems with my YouTube Shorts channel.

Thank you for your help. I'm a newbie to YouTube and English is not my first language, so please excuse any inaccuracies in my description.
I purchased a monetized YouTube account from someone on a forum. The account was originally used for long-form content, but I've been using it to upload short videos. I received a community strike for video violence, which I've since addressed by deleting the offending content. The strike is set to expire next week.
Upon receiving the account, I uploaded 6 short videos, each of which received between 500-1000 views. However, starting the next day, neither my long-form nor short-form videos received any recommended views. This continued for two days. On the third day, only the first short video I uploaded received views; subsequent videos got no recommendations at all, and this has continued for four days.
I'm baffled as to why only the first video received recommended views and reached 1000+ views, while subsequent videos have received no recommendations.
Additionally, I have a separate YouTube channel that I've been running for 10 days. This channel has 100+ subscribers and 90,000 views. Recently, I've encountered a similar issue: only the first short video I uploaded on this channel received recommended views (around 200-300), and subsequent videos have gotten no views. YouTube has stopped recommending my videos.
I'm at my wit's end. Can someone please help me understand what's going on?

Your content and/or thumbnail is not good enough or not unique for YT to promote it further.
Thats whats going on.

Improve the thumbnail and content.
Dont upload for some time, let it rest for few days/weeks.

Then upload again

so which is more prominent content or thumb nail

Your content might not be reaching enough people due to algorithm issue.
Focus on creating visually appealing and high-quality Shorts. Ensure your content is entertaining and provides value.

Create eye-catching thumbnails and compelling titles that grab attention quickly. Even though Shorts are often viewed in a feed, a good title and thumbnail can make a difference.
