I'm getting this problem too, my new module was declined without email notification or comment/explanation.
EDIT:
Update for anyone experiencing this. if you get a technical validation rejection without comment or email notification, it's likely an automatic rejection by the system and the reason is hidden (at the time of this writing). Try the following:
- Go to your "Products" page of your seller account and click the "Validation" button at the top of the page.
- On this page, there will be 2 buttons that are hidden for some reason, and you have to click them.
- The first button is on the right-hand side of your module's name called "Voir Plus"
- The second button is under the module's name called "Contacter l'équipe de validation" (you have to hover over it to see the text)
- Once you click on the second button, it should send you to a page with the rejection reason and a contact form to contact the Addons team.
Here's a screenshot of the two hidden buttons (I had to dig through the HTML source to find them).
