Hello,
I've scoured through the forum posts on both here and the Nintendo Developer Forums and I can't seem to find a clear solution to the issue we're encountering.
We're trying to authenticate users via the LoginWithNintendoServiceAccount API call and it's failing 100% of the time with a 400 Bad Request error.
We're successfully obtaining an NSA auth token and the JSON seems like it's valid. We've also set up our Client ID in the PlayFab Add On Dashboard using our Switch Application ID (minus the 0x prepend).
Is there anything that we're missing here?
Thanks!
