also having this problem on ps4 I tried deleting everything and reinstalling it did not work including save data and cloud save data
I've had this problem for 2 days now and just managed to fix it.
If you go to Settings then Application Saved Data Management, Saved Data in System Storage, Delete. Then delete your apex legends data it should work.
Fingers crossed for you, it worked for me.
EA Support need to up their game as well, as this is quite a simple fix and the gent I spoke to didn't have a clue, just gave me loads of generic test to do.
Thank you for the quick fix. Worked right away. No need to re install game guys just delete the cash and it will auto update when you open
