Hi friends,  
with the last NODE RED i've issues with RBPi's GPIOs.  
I've a setup with Raspberry Pi 2W and two SD cards with the following setups:  
SD1) Linux 5.10.17-v7+ armv7, Node Red 2.1.3, NPM v14.18.1, node-red-node-pi-gpio V2.0.1  
SD2) Linux 5.10.17-v7+ armv7, Node Red 3.1.3, NPM v18.19.0, node-red-node-pi-gpio V2.0.6

With SD1, GPIOs are working, with SD2 not. Same flow (copy and paste).  
With SD2, under the nodes, there are grey square advisories, With SD1 they are green.

What happens?  
Many thanks in advance.

Thanks,  
yes - OK - I think I squished that bug in the latest install script. So it should now "fix" that if run again. (but you have already fixed it so no worries) 🙂
