I found an occurence where the EOS OSS’ IdentityInterface does not return a correct access token (expired).

- I used (`IdentityInterface->GetAuthToken(...)`) to get the token.
- I created a scheduler run each minute to obtain the token and detect whether there is a change or not.
- The access token expiration is 2 hour. But at the end of the 2nd hour, the scheduler didn’t detect any change of access token.
- But, at 3rd hour, the scheduler detected a change of access token which is a new token that was refreshed at 2nd hour.

Is this a bug from EOS OSS or EOS SDK?  
Any workaround to ensure the `GetAuthToken()` can obtain an actual token correctly?

Thanks.

This is a bug that was fixed here: [https://github.com/EpicGames/UnrealEngine/commit/bc74b7b927285bb03080cf7727fcfc47469fe2a3](https://github.com/EpicGames/UnrealEngine/commit/bc74b7b927285bb03080cf7727fcfc47469fe2a3)

A good approach if you want to see if an issue is fixed in later versions of UE is to:

1. Navigate to the API with an issue. Make sure you are in the ue5-main branch.
2. Check the Git Blame (you can toggle from code to blame at the top of the code in GitHub)
3. If there is a change after the version you currently have, look at the change to see what the fix was and in what version.

Be careful with this, I tried to implement code changes from this commit in my 5.1 plugin version and I started to get crashes on dedicated server with an error of NetIds not being of EOS type. NetIds were valid, btw
