When I sign into Guides, I see two instances, example(default) instance, and a Production instance.

I am trying to hide the example(default) instance of Guides during sign-in. I no longer use the (default) instance.

I tried going to powerapps.microsoft.com and under "Your Apps" in (default), I have "Turned off" both Remote Assist and Guides apps.

Interestingly enough,

This has successfully hidden the (default) instance inside of the Remote Assist during Remote Assist sign-in screen!,

but it has unsuccessfully hidden the (default) instance inside of Guides during the sign-in screen.

What to do now?? Where to go from here?

Unfortunately the "Delete" button is greyed out and I can't delete the app under powerapps.microsoft.com Your Apps.

How do I go about removing Guides from the (default) instance so that it does not appear during sign-in?

I am already aware that there is no way I can restrict the default environment visibility using an Azure AD Group (all other environments have this feature, except for default environment)

I am already using the restrict visibility on non-default environments. I wish I could restrict visibility of (default) too....

My (default) environment is still prevalent during sign-in and unfortunately still pops up during Guides sign-in, no matter what I try.

I am only using the production environment and want to get rid of the (default) environment during sign-in. The (default) Guides is "turned off" but it still shows up during sign-in....

How do I remove (default) environment from Guides sign-in screen?
