Thanks @edmonparker the problem got resolved after updating cache from WP Rocket.
I just took the clue from cache plugin comment because it was earlier working perfectly fine.
I still don’t understand why it happened and why it got resolved. But it is resolved now.
I have a similar issue the read more just toggles to read less but does not show the hidden content. No change done on the website except the update of the plugin.
It works fine on Laptop/desktop but not on mobile. Even my customers are complaining Here is the URL. Am checking on chrome browser.
