Thank you for participating in the Samsung Developer Forum. However, this probably is not the correct forum DeX issues. I think programmers use GitHub and end users use the Samsung Community.
I would recommend you use the Samsung Members App for feedback
or
go to https://www.samsung.com and depending on your location
either → Click on Explore Tab → Click on Community
or
Scroll all the way down to the bottom of the page and under support is a link to the community
