Preview issues - lag and out of stock at checkout

Hi all. Is anyone else having issues with the previews today? I’m getting out of stock - items no longer available and other check out and add to cart issues as well as lag. Live site is fine.

Just want to know if it’s my machine again or if it’s happening to others.

Hi @Bar

By preview, do you mean the development theme that you preview locally on your machine when you run shopify theme dev or do you mean theme previews generated from a store admin? Also - are you still seeing this today?
