Weird behaviour with app_remove events

[Brett Romero]

Anyone else seeing weird behavior with app_remove events since 3-4 March 2022? I am working with a couple of mobile game companies (both with apps built in Unity) and I am seeing a huge increase in the number of users that only ever register an app_remove event in both games. No first_open, no session_start, just one solitary app_remove event. Used to be very few users that would ever do this ( <10 per day in a game with 1000-2000 installs a day). Now seeing hundreds every day.

Is anyone else seeing the same thing? Anyone know what might be happening?

it's not that the user only shot one app_remove event, 

but the user_pseudo_id has changed, check the device.advertising_id for reference.
