Hello There!
 
I hope this finds you well. I have checked your caching and it looks setup fine. Can you please check with your theme developer if theme is compatible varnish and object cache? And also ask for their suggestion if they recommend any other cache plugin for their theme. Furthermore let us know if theme requires anything exceptional on server level so we could setup that too for you. Thanks!
 
Kind regards,
Usama Sharfi

Please help me how to troubleshoot this problem, Thank you

Already uninstall the mobile theme & AMP plugin
Everything looks fine on PC and phone.
May I know why this function cannot be turned on?
Dose mobile theme & AM P plugin increase web page speed?

Thank you
