It turns out the current Python library support for the Adafruit PiTFT displays may not work with the 2021-era linux kernels. If you type
{{{
dpkg -l raspberrypi-kernel
}}}
and find the version (which is a date) is 2021 and you want to use one of these displays, if the display isn't working after installation, the solution is to "pin" the kernel version back to 1.20201126-1. This is described in the Adafruit Forum:

...though I note that using the March 2021 beta version of the 64 bit Raspberry Pi OS the display worked
without pinning the kernel, i.e., out of the box.
!! Fail to install tslib
If during installation of the Pi TFT software you get a message stating it had failed to install tslib, here's
a reference to a fix: [https://www.impulseadventure.com/elec/rpi-install-tslib.html] if you're willing to install
tslib yourself. But it seems:
%%blockquote
The issue is that tslib is not available anymore, it has been renamed {{libts0}} (if I'm not wrong), so the provided python script is not working anymore.. I would have expected that Adafruit provide up-to-date installation instruction for the 3.5" touchscreen
%%
...so the solution seems to be to modify the install script by substituting "libts0" for "tslib". That seems to work.
