fullscreenEnabled is false for Safari and Chrome on iOS about fscreen

[JeffreyJoumjian]

Hey if anyone is still struggling with this issue, I found this thread on StackOverflow. Turns out this is an issue with IOS and other fullscreen libraries like screenful also don't do this check. Try doing this:

try {
    // for most browsers, this will work
    if (isFullscreenEnabled()) {
      fscreen.requestFullscreen(element);
    }

    // for older versions of Safari and IOS, `isFullscreenEnabled` will return false even though it is supported https://stackoverflow.com/a/39083376/10626111
    else if (
      "webkitEnterFullScreen" in element &&
      typeof element.webkitEnterFullScreen === "function"
    ) {
      return element.webkitEnterFullScreen();
    }
} catch (err) {
    console.error("Failed to enter fullscreen:", err);
}
