Approval For Posters Is Taking Forever And I've Been Waiting A Month To Get Approved

To begin, I am a displate artist. I was approved to sell my work there about a month ago. I have a backlog of around 40 or 50 pieces I would like to post to my store, but the problem lies in the approval status of my current posters. I submitted my first poster and it was approved immediately, like same hour and everything. I submitted a few more one at a time, one per day, and thought it was weird that these were taking longer to get approved. I thought that it must just be from the back log of work that they have to deal with and that it would just take a few days, the website does say it can take up to 72 hours after all. Well, a few days turned into a few weeks and I was getting frustrated that my posters were just sitting in purgatory like this. I couldn't delete them to try a different one, they weren't getting approved and just sat in the pending status for weeks. I contacted the support team and asked them why it was taking so long for my posters to get approved and they said it was because they were having changes done to the approval system and pieces are taking a lot longer to get approved as a result. It's been a month now and they still haven't budged at all. They haven't been approved or denied, just eternally sitting in pending approval status and it feels like I can't do anything to make it move. There doesn't seem to be any point in me uploading more until I hit the upload limit because they will just sit like that too. I'm at a loss for what to do. Do any of you have experience in anything like this?
