TL;DR: Circle is confirm and X is cancel. 
After being with Ubisoft for 5 years and countless hours in The Division franchise and today making a re-purchase to enjoy the game on a PS5.
I'm truly disgusted that somebody thought it was a good idea to program the version being sold in South East Asia to enforce a button behavior that ONLY makes sense in Japan and give us no option to undo it. Where (O) Circle is confirm and X is cancel.
Yes, it's possible to re-map the buttons under Accessibility under PS5 own setting, but those changes are global. That's big doo-doo for Sony not letting us do that on per-game basis and the Playstore for selling this garbage outside of Japan, but a google search has led me to believe this problem only persists with UBISOFT GAMES while looking for an actual workaround that isn't dog feces!
