Product Description Formatting Error when sync with third party

When we sync our Shopify products with third party apps (TikTok & CommentSold), the product description formatting does not sync properly.

The example below is the HTML in Shopify:

This is what the product description looks like in Shopify:

This is what the product description looks like in both TikTok & CommentSold:

I realize this is a tough fix considering the third party apps.

MY QUESTION: Is there a way to edit the HTML so that when it is synced with the third party apps, the formatting stays consistent?

You need to find out what formatting/HTML the other platforms support.

Then only use the lowest common denominator of formatting/HTML ALL platforms support in the descriptions coming from shopify.

It looks like the 2nd images description ignores
tags.

Further between the two the first image “what the product description looks like in Shopify” is the what the description looks like on your storefront(stores frontend)store predominantly styled by your theme with CSS , which a third party platform never uses.

Which is very different from the rich-text preview seen in shopify in the admin for that resources description.
