Hi, A question on the Azure Web Apps and having all the existing App Settings wiped!! It appears that any non-Pulumi app settings are getting wiped even when Pulumi indicates that it will not be updating the App Settings. This was a Pulumi Preview --diff for a function app of mine. No AppSetting changes indicated. I did the Pulumi Up and all existing App Settings were deleted. Very annoying!! This was after doing a Refresh and then also an Import to ensure all existing settings were discovered. However it does not appear that AppSettings are gathered into state using either. Is this expected behaviour or am I missing something? Ran

pulumi preview --target 'urn:pulumi:qa::gqt::azure-native:web:WebApp::######-func-gqtproperty-qa-ne' --diff

Got following response

Build succeeded.
