CSS effects are delayed in SPFx App customizer

Question

I'm trying to hide the SharePoint App Bar using SPFx app customizer but while loading the page app bar first loads then is hidden.

How can I make the app bar not to load at the first place? Thanks.

Answer 1

You cannot make your application customizer load before sharepoint.

But if you want to hide App Bar, you don't need App Customizer or SPFx. There is a command to disable it (temporarily)

Set-SPOTemporarilyDisableAppBar $true
