Lezavi D.

Thank you for supporting me, I'll check this logic again

I have init the mixpanel with config autocapture and set profile in client side, but to let some sensitive info appear on mixpanel I need to init in backend in order to send these infos to mixpanel (init with token only then use mp.people.set() to send) the flow for tracking user is: user access to app then login -> authen process -> server send userID to client (query user in database then insert sensitive to mixpanel via mp.people.set() in server side only) -> client get userID -> init mixpanel and set user ID as distinctID in client side

as u can see mixpanel detect the location in tracked user but it is undefined in untracked user

And here is untracked user

Here is tracked user

events dont appear for that users who have the geolocation info undefined

Does the untracked user related with the setting opt_out_tracking in mixpanel, due to I did not set this may be it is set to true by default ?

I have set the distinct ID via mixpanel.identify(user.id); in client side After analyzing the untracked users, I see that they all not be captured the geolocation info (Country Code, Region, City) undefined, while these info were captured in tracked users Also here is my proxy config (written in Caddy) <my-tracking-domain> { handle /lib.min.js { reverse_proxy https://cdn.mxpnl.com { header_up Host cdn.mxpnl.com header_up X-Real-IP {http.request.header.X-Forwarded-For} header_up X-Forwarded-For {http.request.remote} header_up X-Forwarded-Host {http.request.host} rewrite /libs/mixpanel-2-latest.min.js } } handle /lib.js { reverse_proxy https://cdn.mxpnl.com { header_up Host cdn.mxpnl.com header_up X-Real-IP {http.request.header.X-Forwarded-For} header_up X-Forwarded-For {http.request.remote} header_up X-Forwarded-Host {http.request.host} rewrite /libs/mixpanel-2-latest.js } } handle /decide { reverse_proxy https://decide.mixpanel.com { header_up Host decide.mixpanel.com header_up X-Real-IP {http.request.header.X-Forwarded-For} header_up X-Forwarded-For {http.request.remote} header_up X-Forwarded-Host {http.request.host} rewrite /decide } } handle { reverse_proxy https://api.mixpanel.com { header_up Host api.mixpanel.com header_up X-Real-IP {http.request.header.X-Forwarded-For} header_up X-Forwarded-For {http.request.remote} header_up X-Forwarded-Host {http.request.host} } } }

It is about 30% users cannot be tracked (no event even I have caught their user ID and set as distinct ID) Here is my tracking config: mixpanel.init(MIXPANEL_TOKEN, { api_host: API_HOST, secure_cookie: true, autocapture: { click: true, input: true, dead_click: true, rage_click: true, scroll: false, submit: true, capture_text_content: true, }, record_sessions_percent: RECORD_SESSIONS_PERCENT, record_idle_timeout_ms: RECORD_IDLE_TIMEOUT_MS, track_pageview: true, persistence: "cookie", });
