Stuck on T25

I thought there was a freeze on tiering up but I'm seeing posts from others being tiered up recently. I have 377 sales and I'm still stuck on T25. All of my design slots are filled and have been for months also.

Anyone know why or what I need to do? The only thing I *can* do is keep adding products. Does that help at all? It just feels so daunting to reach 1950 when I'm only allowed to do 3 per day.
