What causes the delay
This could be due to caching on your server. Caching allows your website to load faster, but it also means there is a delay for back-end changes to migrate to the front-end.
How to fix delay in visible changes issue
Option 1: Contact your host
Step 1: Contact your host’s tech support for options to clear the server cache.
Option 2: Caching Plugin
If you’re using a caching plugin try to temporarily disable the plugin to see the changes more quickly, or you can modify your caching settings to allow for more frequent clearing.
When you’ve made these adjustments and you’re ready to test, double-check your work on an incognito browser to avoid caching on your regular browser.
