Why Facebook on Android blocks JS content from my site?
I have a site with "Drupal 8", "Bootstrap 3.3.7" and "Font Aweome 5.2".
I just realized that Facebook does not completely load the pages of my site on android.
Facebook blocks JS content from my pages.
Here is a page of my site opened with the application Chrome (it is correctly displayed) :

Why Facebook on Android blocks JS content from my site ?
I do not see any problem in the console :
UPDATE
I did several tests to find what causes the blockage.
In the configuration of "Drupal 8":
if the "Aggregate JavaScript files" box is checked, JS is blocked with the Facebook application on Android.
if the "Aggregate JavaScript files" box is not checked, JS works correctly with the Facebook application on Android.
Now, the problem is that for performance reasons, "Aggregate JavaScript files" must be enabled.
Do you have an idea to correct that ?
@Hackerman Thank you I check and I do not see any error. Do you have any information please ?

I also checked here webpagetest.org/result/… and it seems that your site is not fully optimized.

@Hackerman webpagetest.org/result/… I did a test again and it looks good. What should I optimize ? Do you still have errors in the console ? Thank you

The element you're referencing as not rendering correctly is using an 8-digit Hex Code instead of
rgba()
. Have you confirmed if Facebook's baked-in browser supports that feature?– Robert
