Theme slow after update WP 5.3


I noticed that Sydney is very slow after the WP 5.3 update, it is on all my sites where Sydney is running.

Maybe it’s time for an update since in WP 5.3 changed a lot of things. I have downgraded 2 sites to WP 5.1 and now they are running OK again.

Kind regards


Can you please provide a link to an affected website?

Kind Regards, Roman.
