I have the Touch + Case version, a few weeks ago it worked well. I didn't use it for a few weeks, I keept it in original package. Now when I tried it again, touchscreen doesn't work at all. I reinstalled DietPi, still doesn't work. I installed Raspbian and touch still doesn't work. Everything else works, the display works, both USB ports work, but touchscreen no longer works.
I also removed the Raspberry Pi Zero 2W and inserted it back in, and still touchscreen doesn't work. The xinput command shows the Waveshare touchscreen, but nothing happens if i touch the screen. I also tried different power bricks but still touchscreen doesn't work.
The thing is, when it worked sometimes randomly stopped working a few times, but after restart it worked again. But now I can't seem to make it work again.
