Touchscreen Plugin and RPi 3B+

When I installed the Touchscreen Plugin there was a note that said using the plugin with a Pi 3B+ is not recommended.

Why is this true or is the note just out of date?

Does that mean a standard Pi 7" touch screen will not work?

Thanks.

Hi I tried to install the 3,5" touchscreen

GOt the weirdest errormessage, see Picture.
Seems now that installing the driver under Volumio is not that simple as I assumed. Instantly have to say my Linux knowledge’s limited, im good in copying and typing hahaha
Any suggestions? Want to install it in my CAR (yeah).
