We are also facing this issue during the init.
Upon debugging found that the method PersistentIdentity.getTimeEvents() is utilized for retrieving a map containing event names mapped to their respective start times, represented in milliseconds since epoch. This map is subsequently stored within the variable mEventTimings.
Mixpanel#getInstance is suggested to be called from the main thread as per the doc :
"The best practice is to call getInstance, and use the returned MixpanelAPI, object from a single thread (probably the main UI thread of your application)."
But this blocking IO call is happening on the main thread.
