I have the web viewer block that links to this YouTube video: https://www.youtube.com/embed/QvgwVxunufs?playsinline=1
It appears the “playsinline=1” parameter doesn’t work in the web viewer block. The video formats great in my app, but when I hit play it plays it full screen. The “playsinline=1” parameter is supposed to tell iOS to not play full screen, but it does. This happens in the Thunkable Live preview, as well as the native app.
I see the problem you’re describing but I don’t have a solution. It seems like Thunkable is launching its own media player rather than using the Web Viewer for that. So I think that’s why the video is still full screen.
