ovr-platform-util: This platform has been discontinued

Hi,

I tried uploading an dlc file via add-ons and the CLI ovr-platform-util (newly downloaded today)
./ovr-platform-util upload-add-on 
--app-id 123123123
--app-secret 123123123123
--sku test_sku_001
--file the_file_path

But I'm getting this error message in the command prompt.

Retrieving app info...
Platform: ANDROID

Uploading...


ERROR: This platform has been discontinued. Contact Oculus support.
(translated so might not be 100% accurate to the english version)

What could be the reason here?
Is the platform really discontinued=?
If so, how do I upload add-ons and manage things for the app?
I'm using this: https://developer.oculus.com/manage/applications/{id}/platform-services/add-ons/
