Product Images Keep Being Removed

We have a listing that has been having issues with product images recently. This product had these pictures up on my listing for over a year now with no issues. A few weeks ago all of the product images were removed from the listing and put the product into search suppression. We figured it was some kind of glitch, and we re-uploaded the photos and moved on. A few days later, just the main product image was rejected. We have looked at all the image guideline and know that our image fits within those guidelines.

​

I have now contacted support multiple times for them to just tell me nothing is wrong with the pictures and everything should be fine, but this keeps happening over and over. The next day all of the pictures or sometimes just the main image are removed. Support even reached out to an advisor for me who also said nothing was wrong with the images.

​

What can we do here? This is our best selling product and it is killing our sales going into a very busy time of the year. Any help anyone can suggest would be much appreciated!
