As a solution partner for nopCommerce, we suggest that while submitting a new version of existing extension for review, there should be option for uploading new version of the extension and our points on the solution partners page should not be affected. Also want to take in consideration that users should have an option to direct update the version.
We suggest that there should be whole separate process for publishing new version of extension on the nopCommerce marketplace.
We hope that our feedback is taken into consideration.
