Hello there,

We could not understand why the product we worked on for a long time was rejected.

“Thank you for your submission. We have completed our review of “omtanke - React&HTML Bootstrap 5 Dashboard UI Theme” and unfortunately we found it isn’t at the quality standard required to move forward, and you won’t be able to re- submit this item again.”

This was the answer, but we would be glad if anyone who has an idea about what is meant by quality can help.

Do you have any ideas?
