I just want to bump this. Even after a few FGU updates and today's SW update, Chase Mode does not appear to work (rewatched DOSWALK's video, turned on chase mode, cards show as chase tokens on the map - but range is still as normal mode and complications do not post in chat on a Club action card).
SW: v5.2.9
FGU: 4.0.1 2020-11-11
The screen capture in the previous post is still accurate.
