I bought a Pi for another project and it has not been stable. I thought I was doing all the right updates but did not know I needed to manually update the bootloader firmware separately. I found this guide:
That Pi has the new C0 stepping processor and it had a Feb 2021 Bootloader. The latest stable is April 2021. I just followed the link above to update the boot loader. Hope it addresses the stability.
What are others using for Channels? My Channels Pi4 is a B0 and I've left it on a Sept 2020 firmware since it's stable. Thanks.
