Because that’s the API route when you try to access a page, which you can see in the network tab when you open a page in the Panel, e.g. api/pages/notes+across-the-ocean
$route->arguments()

<pre>Array
(
[0] => pages/notes+across-the-ocean
)
</pre>
What do you mean with “only after reload”. If you are on the dashboard and try to access a forbidden page, it should not be accessible. See this gif:
