The latest version of SBrick application can't connect to SBricks. I reinstalled version 4.4 Update 13 and now it's working again...
I haven't tried previous versions of your application so I can't tell if they work or not. I would really appreciate if you could check and tell me what to do because controlling Lego sets with PS4 controller seems so much more comfortable...
By the way, from SBrick I didn't get any answer whatsoever, just a reply from a user on their forum...
