Sign-in API call results in 403 - You are forbidden to perform this operation

[JeffResc]

POST request to /users/sign_in.json is now resulting in a 403 with the error "You are forbidden to perform this operation" with no reason as to why this API call is no longer functioning as it originally was.

I have confirmed that the app_id and app_secret constants seem to still be correct as changing these values will instead result in a 404 as expected.

@JeffResc
I have a mitm capture I can provide of the Shark APP logging in if this helps. I threw together some python code to try to copy the flow that the APP uses but no luck getting past the Shark login. Contact me directly if you want.

Anyone formally reached out to Shark to complain? This is a violation of their product terms; We purchased it with access to the API, they can't legally revoke it.
