I have uploaded update version of my addon and then delete the previous version… now facing delay process of review. Can any one suggest what can i do now… except long waiting… 
What was the addon name? Link to the page on AMO (addons.mozilla.org) would help out the most.
Link to previous addon would help too.
Did you read the warning on the confirmation dialog before deleting the version?
Deleting a version which has already been reviewed may also cause a significant delay in the review of your next update.
