After more than two and a half years, I have to insist on this old problem… Eventually, maybe somebody will fix that in PageSpeed Insights for Mobile and Desktop too:
„Best Practise – Uses deprecated APIs – 1 warning found: Synchronous XMLHttpRequest on the main thread is deprecated because of its detrimental effects to the end user’s experience. For more help, check https://xhr.spec.whatwg.org/.”
