When I am applying changes in functions.php , the changes in the relevant page (e.g. shortcocde) sometimes are not reflecting when I refresh the page.
It can take several “page refresh” (cmd+shift+r) or even 1-2 minutes for the updated content to appear.
Note that I do not have any cache plugin enabled and I am logged in.
Please advise if that’s a configuration issue, or something within the theme behavior?
It happens for me in local development on my local laptop.
Other WordPress sites not functioning like this, therefore I thought it relates to the theme.
that sounds like a caching issue. Whether that be the browser ( use Incognito browser to mitigate caches ) or your local server ( check in its settings ).
The Theme itself won’t get in the way of your custom functions
