I have been using my Galaxy Tab 10 as my primary system, connected to a 27-inch monitor. Additionally, I use a Nexdock smaller monitor alongside it as a second display, to which I connect my Galaxy Fold 6. I use Multi Connect to control both devices with a keyboard and mouse.

I recently upgraded to One UI 8 on my Fold, and I forgot that this software has an updated version of DeX. Surprisingly, when I connected my phone to use it as a second monitor, I could not connect using Multi Connect. I checked the settings under connected devices on my tablet, but my phone did not appear. 

When I examined my phone's settings while connected to the monitor and tried to start Multi Connect, I received a message stating, "Multi Connect and DeX cannot be used at the same time." I disagree with the claim that you can do more with the new Samsung DeX, as it seems I will do much less with this update.

Are these issues being investigated? Is there a non-Windows, software alternative for doing this same task, while waiting for a fix if any is to come.
