I have prepared for the upgrade by reorgnizing the keyowrds into proper categories. However, auto-upgraded few days before, all things were in a mess. YSM used my ad title as the ad groups name, and put my keywords elsewhere, the ads cut into half etc.

Do all using YSM experience the same problem? Any fast way to reorganize the whole account?

If I delete all and upload the new listing, how long will it take effect?
