I have UWP app backend is azure mobile app service. I have configured azure b2c as authnetication. from last six month it is working fine.
on my client side i am using DefaultManager.CurrentClient.CurrentUser.UserId which give me userid {sid:value} format.
on server side this code was also giving {sid:value} and provider was aad
var identity = User as ClaimsPrincipal;
var userClaim = identity?.Claims.FirstOrDefault(b => b.Type == ClaimTypes.NameIdentifier);
from 20 December it is giving directly from b2c.
when i send the same request to local code it works as expected. but if i debug using attaching to azure mobile app. i am getting the same different value.
Now from 21 Jan on server it is again giving userid as {sid:value} format.
what is the correct format i can not keep changing my code.

What different value are you getting? Sorry if I misunderstand, but can you clarify what the expected outcome is and what you are receiving?
it is not about the value it is more about format.
earlier it was user id was {sid:guid} which generated i think based on some algo. this is called stable id.
then it again started giving the userid as only guid this time is from Azure AD B2C identifier.
on 20 Jan it stated again giving the stable id in {sid:guid} format.
i can not keep changing my code. my users stopped getting data.
Hi @Ryan Hill any updated since i am stuck and my users are not able to get the data.

we are also having the same issue - this is a major change management issue and we need this to get resolved ASAP also - our users also cannot retrieve data. What is the root cause of this issue. this is a MAJOR problem.
mid - december we also found our code was not working which was fine for the last year. my developer found that MS had changed the format as above and then we fixed our code - note there was NO change log from Microsoft communicated about this major impact change.
now since last week something has changed again.
Please elevate this issue to your Critical 1 issue list!
