I wish to add the brand logo on the product page but somehow is not working. I did all the required changes but nothing changes (screenshot attached). did I miss anything?
It seems that you are using any third-party plugin for the product variations that is causing the issue.
Please deactivate all the third-party plugins activate the parent theme then clear cache and check back.
If the problem continues then leave all the third-party plugins and provide with the admin panel login details of the website with the permissions to debug then we will troubleshoot with the theme plugins.
