Delay in loading the initial page after splash screen

Can anyone possibly tell me why we have a couple of seconds of delay on app startup in the ionic 5 capacitor app? Is there any way to avoid the white screen after the splash screen and root page ?

As far as I know, the application is started first and then the dom is created. For this reason, you may be seeing a white screen for a short while. However, a screen recording would be good to better understand the problem.

One launching the application the splash screen shows up , then a white screen for 3 to 4 seconds . Only then the root page is loaded (my login page)
