My product was rejected as a result of review.
The reason is that it does not meet the quality standards.
What should I do ?

Preview link :

dashboard = Market Laravel - Login
Admin Email = admin@atozweb.site
PASSWORD = 12345678

seems the interface is too old design. you should apply with latest design

Thank you! Many additional themes will be designed, and the main theme will be improved. What do you think of the design of the admin panel? I didn’t rely on a pre-made design, but instead, I designed it using only Bootstrap.
