I want to change the date format to yyyy/mm/dd.

Hello,

So far we don't support yyyy/mm/dd.

You can check list of timestamp format in your Review Timestamps setting: https://judge.me/settings?jump_to=review+timestamps

This is a good request though and we encourage you to post it in our forum for requests, so other shops can comment and vote on it https://judgeme.featureupvote.com/?order=popular&filter=allexceptdone

Best,

Kien Tran
