I need to create Magento 2 extension that will be adding some content (information) to products on category and product page, that information will update depending on the configuration of extension (date-time range) I want to find the best solution, which is better, clear cheche by tags when I need to update my custom content or load it content by ajax? I think a clear cache is a better idea such as loading my custom content is a little bit hard process. Are you have any idea?
