As we all know, there are 2 postMessage methods in Velo (iframe and window). I have been using wixWindow.postMessage for ages to send info to the frontend client to inform it about query start-end. wixWindow.postMessage, by default, posts to Parent. This has been working ever since. Until recently: it still works on desktop browsers, but, alas, on Mobile it is working no more, this is a dead window, it is pushing up the daisies.
I have been trying this on Chrome, Edge and Opera, all dead. But…, they all are Chromium based. So my question is: is this a Velo thing or a Chromium novelty?
Any serious answer would be highly appreciated, kind of stuck.
