Studio Theme- No H1 Tag Issue (Homepage, Products)

We are utilizing Shopify’s Studio theme and have recently employed numerous SEO optimization tools for our website. Upon inspection, we discovered that all of our web pages lacked an H1 tag. This poses a significant challenge for both SEO optimization and myself.

Firstly, we would like to inquire about this issue and seek guidance on how to best resolve it. Are there any instructional videos or text tutorials available?

Secondly, we respectfully request assistance from Shopify staff. After all, we signed up for this service with the intention of making our business operations more efficient and streamlined, did we not?
