When i open the app i have that is connected to my site then i get a 404 error but when clicking one of the navbar links the app works normally.
I use Alpha theme and the plugin I use for the mobile is osc_mobile.

Can someone explain me why this keeps happening? Also this bug is not on all the devices i tested in a iphone 15, 14 and a 11 but i only got the error in the newer phones, 11 does not have the bug

@Jelle
Not sure if it's really good to use mobile plugin, it's bit older and was good 10 years ago.

Is their another plugin for mobile? If yes can u suggest some.

No such plugin is needed nowadays.

Okay.

I will try to do it without the plugin and with code only
