Product Image Fuzzy – Wrong Size

After the latest update: I found that when I created a new product in my shop the image appeared fuzzy – even though it was the same size and resolution as the others. Turned out WooCommerce was displaying the 300×300 thumbnail when the others were 600×600. I had to go back into CUSTOMIZER->WOOCOMMERCE->MAIN IMAGE WIDTH and reset it to 600×600.

I don’t know how or why it changed. Just documenting here in case anyone else had the same issue.
