You can disable the :ref:`CONFIG_DESKTOP_FN_KEYS_BUTTON_EVENT_SUBSCRIBE_FIRST <config_desktop_app_options>` Kconfig option to use early subscription (:c:macro:`APP_EVENT_SUBSCRIBE_EARLY`).

Should we also write known issue here for our applications or will it be in other PRs?

I will create known issues once the fix PRs are merged (for other projects as well).

Previously, it was assumed that the memory size for this board target was 10 KB larger than the actual one.
The NVM size in the nRF54L10 SoC is equal to 1012 KB.

This change in the nRF54L10 partition map is a breaking change and cannot be performed using DFU.
As a result, the DFU procedure will fail if you attempt to upgrade the sample firmware based on one of the |NCS| v3.0 releases.
