I’ve seen same behavior in Magento 2.4.3 and now in 2.4.4
I upload products via API.
When product name contains characters as “%” (percent), “,” (decimal) and non latin characters, in corresponding image name they are replaced by “_“.
In such a case, image types (base, thumbnail…) are not set or set only in one of scopes/views. I’m not completely sure whether these two are related to each other, but that’s what I’d noticed so far.
Is there any way to set image types and get them displayed in frontend and backend list (thumbnails)?
