Hi
we are evaluating Mixpanel for our report, and we would like to import our existing users' profiles using CSV import, keeping the previous history.
I have a few issues with importing.
I cannot set up the first/last seen properties of the user.
I tried mapping the CSV columns to $mp_first_event_time
and $last_seen
but this does not work.
I can see the values in the single user's profile page but I cannot breakdown against them in the reports, or even seen them in the profiles' page columns.
Below an example of CSV row:
"563241f023ac4fdaaa37defed415d248","563241f023ac4fdaaa37defed415d248","2021-31-13T13:10:00","2022-23-24T08:05:00","premium","Skytale"
and the results as seen on the dashboard:

and from the `/engage` query, compared with a profile created from the identify call from Segment
{
"$distinct_id": "9b674afc-cc22-4df1-9945-fad7766af464",
"$properties": {
"id": "9b674afc-cc22-4df1-9945-fad7766af464",
"organization": "SKYTALE",
"plan": "premium",
"$last_seen": "2022-06-09T15:51:10"
}
},
{
"$distinct_id": "563241f023ac4fdaaa37defed415d248",
"$properties": {
"$last_seen": "2022-05-24T10:05:00",
"$mp_first_event_time": "2021-10-13T15:10:00",
"id": "563241f023ac4fdaaa37defed415d248",
"organization": "Skytale",
"plan": "premium"
}
}
Please, any help will be appreciated.
Thanks in advance
