Waiting for approval for 4 months

No one knows why some assets are ignored for many months while others are reviewed much sooner. Unfortunately Adobe is silent on this issue.

i have the same. while most of my pictures get reviewed in some days some seem to stick..

Yes, there is an issue. Some of us are waitingh for a year or so. There is nothing you can do, except deleting and resubmitting or waiting for moderation.
