product-image.php template file cause Single product image size problem

Can you give an example link to one of your products that has the problem?

Here is example link https://www.taktika.lv/store/product/powerslide-x-fire-rollerski-2/

If I roll back to previous product-image.php file it’s displaying 600x600px image like I have set up in settings panel

What did you do to update the templates?

Does this issue exist when switching to a default theme temporarily?

I moved new template files from:
wp-content/plugins/woocommerce/templates/single-product/
to
wp-content/themes/legenda/woocommerce/single-product/

Issue exists when switching to any of default themes

It looks like Legenda theme doesn’t support these two new template files. Theme author suggested to skip this notification about outdated templates

Ok, they will need to bump the version once they have ensured it’s compatible.
