Hmm, I don't know enough to give you a confident answer yet. However, you might want to check the following documentation for more details on identity management and potential issues with user IDs in Mixpanel: - Identifying Users (Simplified) - Identifying Users (Original) - Identity Management OverviewThese resources might help you troubleshoot and understand why user IDs might not be set as expected.
kapa.ai is still learning and improving, please let me know how I did by reacting below.
