Hello,
Yes typography dropdown list is working good now.

Sorry for misleading you. Yes H1 is used for product title and it’s ok. But in the product description field I want to use H2 for the first line of product description.
No matter what typography parameters I set for H2, no changes appear in the product description field.
Firs line of the description which is set as H2 is always uppercase and doesn’t respond to the settings of the typography.
