Signature generation and meeting join issues in Meeting SDK using Server to Server (s2s) oauth app

[Dev_Declan]

I created a server to server oauth app and created a signature for the meeting SDK using accountId, clientId, and clientSecret.

And when I tried to join using the signature, I got the value signature is invalid, errorCode: 3712.

Is there a way to resolve this error?
Please let me know. This error cost me about 3 weeks.

I have the same issue with S2S OAuth App.

I've also tried generating the signature with the sample app they provided, and I get the same error.

I thought being on localhost was an issue, but joining the meeting via client component on Web still ends up with 3712 error code.

Not a great DX.
