Hi,
I encountered a problem as this subject mentioned. After tested in the GTMetrix and PageSpeed Insights both, it showed [Avoid serving legacy JavaScript to modern browsers] this issue. And the symptom of this issue is [Array.prototype.includes].
I attempt to disable Ad Inserter this plugin, this situation was gone!
May I have your any advice to resolve this?
<PS> WordPress version:5.8 / Ad Inserter:2.7.3 (no insert any Ad codes)
Thanks for help in advance!
