AWS CognitoIDPClient.InitiateAuthAsync not returning a callback

The CognitoIDPClient.InitiateAuthAsync function doesn't return a callback on Oculus Go (android), but on standalone, editor, android, and ios it works fine. This causes me not to be able to log into my project.

I am working on a project using Amazon as a login service, but having some issues on the Oculus Go. The code runs fine up to the point of the function call, and after it (since it is async), but the callback that I am supposed to get never arrives. I am connected to internet on the Oculus.

Unity ver: 2019.1.3f1
