Hi.
I can also confirm that the nacon ps4 compact controller work with Xim Apex. I used it the past month or so playing Destiny 2 (ps5 edition).
That being said I do have a issue with my Sony nav. Since I first updated to, earlier version of the new beta firmware for support for xim apex on ps5, I had issue where my Sony nav would stop working time to time. I had to plug xim apex out and back in. I ended up always trying to get it work in wireless mode, which worked fine but sometimes I just couldn't get it into wireless mode. I have never had this issue before and I am been using Sony nav with Xim apex since it came out.
Just now I updated the firmware of the xim apex to 20210223, and now when I plug in xim apex, whith Sony nav already plugged into it, the xim apex start blinking red and yellow. If I plug in xim apex without Sony nav, everything is fine, but as soon I plug in Sony nav to xim apex starts blinking red and yellow. I also get the following message in the manager: "Power Fault, The devices plugged into your XIM APEX are consuming too much power and all were shut down. Please diable lights and ensure devices are charged and restart your XIM APEX."
If I plug in Xim Apec with only Sony plugged into it, I still get red and yellow blinking. I was able to partially use my Sony Nav before this update, but now its fully dead.
I also tried to replace sony nav with my Ducky One 2 mini keyboard, but Xim Apex doesnt recognize it as a device.
