I reinstalled the game, and lost all of my progress, can anyone help me get it back?
No clue if you can get it back, but I had the exact same thing happen to me. I reinstalled Windows 10 after the Anniversary update messed some stuff up and lost all my Apex progress. I have all the cloud stuff turned on for data syncing, logged in to my Xbox profile, nothing in Windows to shut down telemetry or processes of any kind.
