Recently I Submit my first template but they gave a hard rejection.
Template URL: http://demo.epilogtheme.com/mightshop-html
Note: Total HTML, XD and Figma Almost 6-7 Template Was Rejected. 
You are an exclusive author and also selling this on another marketplace - it will never be accepted while breaching your author agreement with envato
When Reject this template then i will upload another marketplace. Its wrong ?
Depends on the marketplace and the author agreement but for envato you cannot be exclusive and sell elsewhere
You are selling the exact same template on another marketplace.
This will potentially be a reason for rejection here. You cannot be an exclusive author here and sell the same item on another marketplace.
Right now any solutions. I want to upload more HTML, XD and Figma template.
Create one which is not sold anywhere excpet here
OR
Make yourself a non-exclusive author (lower earning %)
who know another marketplace ?
