Hello,
Thank you for contacting the support, and sorry for any inconvenience that might have been caused due to that.
There are no special instructions for doing product SEO but you can follow this one to optimize your product pages: https://rankmath.com/kb/score-100-in-tests/ (but do not follow them religiously, these are just guidelines)
Then, check your WooCommerce SEO specific settings at WordPress Dashboard > Rank Math > General Settings > WooCommerce SEO. Make the changes there as required.
Finally, go to WordPress Dashboard > Rank Math > Titles & Meta > Products and choose the appropriate template for your product titles and Meta descriptions.
Most of the SEO is automated and even the Schema is added automatically.
