Newly created apps return "Signature is invalid" 3712 error code

Meeting SDK Type and Version
Meetingsdk 3.1.6

Description
I already have an application that is working as intended. I wanted to create another application to have a different environment where I test. I swapped both the Client ID and Client Secret. I made sure that the key that is passed to the SDK is the same one I used to generate the token.

Simply swapping to my older credentials (Client ID and Client Secret), allows me to join the meetings again.
