ChatBot AI Data Training

My manager doesn’t like Pdf files to be the knowledge base of AI since Pdf is not easy to be updated by itself and prefers to use URL of web pages. However, there are some web pages Hubspot AI cannot recognize, like this page. https://www.norsat.com/products/3000-c-band-single-band-pll-lnb?variant=41050456817847. After it is synced, the specification of the product is not extracted from the page. Did you have the similar experience? Thanks
