Hi @leopard330, thank you for the feedback. However, this review is inaccurate as the Stripe plugin has always had the ability to use Payment Elements, which replaces Source API when you activate the updated checkout experience.
Also from version 8.0.0 released last month, everyone who connects Stripe to their site via this plugin automatically uses Payment Elements while merchants who were previously connected via the Source API can switch by enabling the updated checkout experience.
I recommend reaching out to us for clarification in the future before leaving a review as it could mislead others.
