Hello!
I have installed recent software update (as of 2020-09-1) of Galaxy Tab A 10.1 (SM-T510) .
Before that update I was able to remote control the Tab from my PC or my smartphone. But after the Android updates, I cannot remote control any more.
I have installed too Universal Add-on, but it works same, and I cannot install Samsung Add on.
Please let me know how to solve this issues.
