I’m uploading replacement category images via a Magento 2 admin interface after deleting them from the server via FTP (since I’m using the same filenames). Most of the images update correctly after everything has been reindexed and cached in Magento and purged in Cloudflare.
However, there are still a number of category pages where the images have not been updated. When I download those files from the server via FTP, they are the correct ones (different dimensions than old files) so I know that the import worked. I have cleared browser cache and double-checked the server for duplicate filenames, but nothing has worked. I thought that the purges on Cloudflare would eventually yield the proper images, but it’s been a few hours and they still are not correct.
