"Set-PnPSite -DefaultLinkToExistingAccess $false -DefaultSharingLinkType None" doesn't work with App Only connection

[hicotton02]

Connect-PnPOnline -Url "https://xxxxxx.sharepoint.com/sites/yyyyyy" -ClientId "[GUID]" -CertificatePath "C:\Users\test\cert.pfx"
Set-PnPSite -DefaultLinkToExistingAccess $false -DefaultSharingLinkType None

When trying to run the two commands above, they both act as they successfully run. I do connect to the site and am able to do a "Get-PnPSite" and return the correct URL, but when I send the 2nd command, it completes after a short pause, but the UI shows no changes.

im using PNP version 1.12.0

also, manually adding the -Identity parameter with the site url changes nothing

what was the reason for making this a discussion? I think it really is a bug... or im missing something dumb
