[tag:nokia-9] has been added to https://android.stackexchange.com/questions/230890/how-to-enable-an-always-on-display-mode-in-nokia-9-for-just-notifications, assuming if this issue is specific to Nokia 9.

There are no other questions that I found to be specific for Nokia 9. Unless https://android.stackexchange.com/questions/229468/how-to-force-a-smartphone-to-do-update, is a specific issue to Nokia 9, feel free to tag it. Otherwise, I prefer to let it tagged with the general [tag:nokia] if it's Nokia policy, or remove the tag altogether if it's known for multiple brands.
