Issue in OAuth 2 tokens expiry

[#1]

Hi,

I am using password grant type for generating tokens. For testing I have kept the expiry of access token and refresh token as 3 and 5 minutes respectively.
I am getting peculiar issue where in even after the access token is expired Verify Access Token OAuth v2 Policy is validating is successfully. I am intermittently getting data and access token expired message.
Same behavior is observed while renewing the access token with the help of refresh token.
Any pointer on this issue will help.

Thanks,

Vinita
