Hi, unfortunately I need some help again. My website is suffering from a growing FID since about 3 weeks and I don't find a way to stop or even reduce it. The FID is now about 203 ms and no hope that it stops here.
I have removed all render blocking CSS.
I have removed all render blocking JS, except JQuery because it is needed by some applications. Unfortunaley it leads somestimes to the info reduce main thread work on mobile devices. (Growing FID was already a problem before that action!)
I have minified CSS and JS.
I have deactivated Social Media Sharing for a splitt test. No difference...
There is no problem with Time to Interactive or Total Blocking Time. Both are green.
What is causing the FID? Maybe someone can help me.
