The 64-bit version of HA OS on Raspberry PI 3 currently asks a lot of memory resources. When you add some add-ons and integrations you can easily hit the limitations of this device. You can find a lot of reports about that in communities. Therefore the documentation should state that the 32-bit version is still the recommended version, because on that it really runs smoothly.
I can confirm the 64-bit version gives a lot of problems on Raspberry Pi 3.
Switching to 32-bit drastically reduces ram consumption (by half!) and everything works smoothly.
The current recommendation gives an awful experience with a lot of crashes.
100% agree 32-bit should be the recommended HASS version for Rpi3.

I’m still on 32-bit bullseye on my rpi 3b+ with homeassistant and other packages running in docker mode.
I also have pihole and cups printing server running on it.
However, I read that containers can perform better in 64-bit, and some packages - like swag which I’m using - has deprecated support for armhf…
so is it not worth the upgrade to 64-bit?
