Different devices have different levels of support. Support for the H700 (the chipset in the CubeXX) has been added a few months ago and the project is still working out the kinks.
Unfortunately we're often limited by whatever blobs the manufacturer provides and whatever is supported by the mainline kernel, as you can imagine there's not a whole lot of people experimenting with the latest and the greatest on these devices so the project often runs into regressions when upgrading. I wish the situation was better but given the prices these devices are going for it's a small wonder they work as well as they do ;) Having (some) mainline support does mean that we'll see updates for years and years so with a bit of luck the situation will improve over time!
For reference the Rockchip devices (RK3266 and RK3566) have been supported for longer and offer a general smooth experience. I've had pretty good luck with my Powkiddy X55!
With regards to 2, just like bazzite and some other distros Rocknix uses a read-only filesystem, you can use mounts to allow certain paths to be overwritten. The default configuration strives to find a balance between allowing some customization and stability.
What you're describing does sound like a bug, it might be that some flag is set incorrectly. I would recommend dropping in at the Discord.
