Sometimes the store gets stuck on the images and deleting an image does not remove the product category thumbnail version, so you can have two completely different product images in category and product page. And uploading a new product image does not generate a new one leaving the product category image version with a placeholder.
Preconditions (*)
- Magento 2.3.3
Steps to reproduce (*)
Don't know. Happens randomly like most other Magento 2 functionality.
Expected result (*)
Category product image should update.
Actual result (*)
Category product image does not update, showing old version.
