Looking for your legacy settings page when clicking on Advanced Settings?
With the whole Dynamics 365 & Power platform becoming app centric, it is getting harder to reach the Settings page!
Till last week you were navigated to the traditional settings page when you clicked on Advanced Settings from your custom app.
Now when you click on Advanced settings, you are navigated to the power platform admin URL,
From here, to open the legacy settings click on Resources -> All Legacy Settings
And you'll find what you are looking for! Hooray!
Or you can directly navigate to settings using this link:
https://<environment url>/main.aspx?settingsonly=true
