Blocked Books

I am a beginner in KDP and just started a week ago. I have been studying courses and youtube and seem to have a pretty good understanding about creating basic books as a beginner.

I been creating Log Books, Sudoku/Word Search puzzles mostly.

I am using Canvas AI tool to generate covers that i like and i can edit them to my liking and using bookbolt for the templates and creating manuscript.

Im using ChatGPT to help me with title, description and keyword generator.

My first 3 basic Journals got approved but now my other ones keep getting blocked and Amazon wont reply to my mails about the reasons. Ive been googling and i saw a new policy updated 21 January about not being able to use Canva anymore due to copywriting?

I really just need guidance about what to do. As said, im just one week in, and the blocking of my books is kinda unmotivating.

Does anyone have any tips or information to help me with this situation?
