Hi @development6,
Welcome to the Auth0 Community!
Can you try specifying an audience value? Example on how to add audience: auth0-maui-samples/Sample at main · auth0-samples/auth0-maui-samples · GitHub
This Community post and thread discuss tokens and why “Invalid Signature” is returned: JWT token is "invalid signature"? - #7 by kkrp1
Please let me know if you have any additional questions!
Thanks,
Mary Beth
