Hello,
I am having an issue where after enabling telemetry in a BC environment, the pageviews telemetry event type is not capturing the user_id field. However I can see this user_id field correctly populating on the traces event type.
Microsoft support agent is saying that only 'certain' events include the user_id field. Is that really true?
Background Info:
- Happening in both Sandbox / Prod environments
- All users have been assigned a 'Telemetry ID'
- Have tried regenerating the Telemetry ID for each user
- Also have tried disabling / re-enabling the entire telemetry functionality within admin center
- This functionality was working as expected all the way until the middle of Nov 2025 as I can see user_id values getting populated until then. After that point, the user_id field is now blank for all pageview events.
Has anyone ran into this and found a solution? If not, what are the possible workarounds to include the user_id with the pageviews? Otherwise this functionality provides little value.
