During the migration of our instance from version 1.57.0 to version 1.59.1, we lost the lastLoginInstant data for almost all of our users.
After checking the database, we found that this data had been set to null in the user table.

Is there a known bug logged regarding this issue?
Is there a procedure available to restore or reconcile the data?

We have since upgraded to version 1.62.2. The data updates for users who log in again, but it remains missing for users who have not logged in.

Thank you in advance for your feedback.
