A third-party summary of Shopify’s Winter ’26 edition says merchants can “schedule and test different themes in real-time” from the admin. That is useful. But the same summary gives no setup steps, plan requirements, or detail on how results are measured, and it is not Shopify’s own documentation.\u003C\u002Fp>\n\u003Cfigure data-post-media=\"6aebd46bcb6b554bc882b623\">\u003Cvideo src=\"https:\u002F\u002Fmedia.stufio.com\u002Fmedia\u002Fasyncshop\u002Fmediagen\u002F6a\u002F6aebd46ccb6b554bc882b629-0-78172f43.mp4\" autoplay muted loop playsinline preload=\"metadata\">\u003C\u002Fvideo>\u003C\u002Ffigure>\u003Cp>So before you rely on any theme-testing feature, decide how you will judge the result.
