In aligning with Blink’s intention to remove powerful features on insecure origins, we plan to deprecate and remove support for the Presentation API on insecure contexts. PresentationRequest and PresentationReceiver where deprecated on insecure origins in Chrome 61. Removal is anticipated in Chrome 72 (February 2019).
