My header used to load large and remain that way until you started scrolling down, then it would go smaller. But now it briefly appears at the larger size and goes small without the user scrolling down. How can I fix this?
Please make sure you are using latest version of it.
Also, this can be due to plugin conflict on your site so please try temporary deactivating all plugins except Unyson plugin and WpBakery page builder plugins and see whether everything works fine and then enable the plugins one by one to see which plugin is conflicting if any.
