If you are only getting 200-400 views on your videos, the account is likely to got shadowban already.
From my experience, I build hundreds of accounts daily, but any accounts that are getting under 500 views under a week per video, it is already considered to be exclude from my project.
Only accounts that are getting over 500 views per video are considered worth continue to work on to have a high chance of viral for that type of account,
Once it is gaining more traction from viewers, it will have a high chance to get millions of views later on.
To fix this, you should focus on your set up the account and making sure that you don't rush in any stage of setting up the account before you posting content on it.
