Defer javascript blocks mobile loading

    Hi,

    GT Metrix reports that I need to defer Javascript on this site: https://gtmetrix.com/reports/eurospa.wpengine.com/OqeJTGdb

    When I set Async Javascript to Defer, the site will not load completely in mobile – specifically iOS X in Chrome browser. I haven’t tested any other browser.

    I have left it set to DEFER for now. I don’t know how to test the javascript console for mobile devices, so I can’t tell you what it might say.

    But I did take this screenshot from the desktop: https://cloudup.com/c_Wuxg8lW7x

    If I disable Defer, then I get the warning in GT Metrix again.

    Whoops, sorry. I must have had some weird connection issues. This may not be an issue after all.

    But now that I look back at the GT Metrix report, I did DEFER and it still shows the issue in the report. Let me dump the cache and see if that will help.

    Now, it’s happening again. Once I cleared the cache, it’s taking forever to load the background video and the rest of the page.

    Okay, one more email on this. After disabling and enabling all my plugins, GT Metrix is no longer reporting this issue. However, the loading issue still persists.

    debugging on mobile can be hard, I usually do trial and error myself Tony 😉

    I would:
    * optimize (and defer) local JS with AO
    * use Async JS for 3rd party JS, deferring if possible, (maybe excluding some JS, e.g. for the video loading) and asyncing if needed

    hope this helps,
    frank
