Our team is switching to GTM and using the Snowplow template. However we are seeing a critical issue when using the setUserId command in GTM, please see the screenshot below:
As you can see, right after the the account_sign_in event, the user_id was successfully set. However all the rest of the events’ user_id turns to null again.
This is very unstable when I was in debug mode. Not sure if it is some issues with GTM or would it be the issue of the snowplow template in GTM.
Please shed some light, thank you
