Well it's wierd bc a few days ago I was charging my phone like I always do at home on the counter and when I went to take it off of the charger I noticed that Samsung apps was updating a whole bunch of apps that I didn't even know existed. I'm assuming this has to do with the new Bixby update. but I think it may be just updating itself to prepare for when Bixby actually does release?
As far as I know, this is activated Server side, in such case, there's no way it will work unless you share the same Samsung account than a current participant.
