2023103000 was replaced by 2023103100, so the "wait a couple days" clock got reset. In general all that's necessary to get an update is to wait until your device fetches it. The main exceptions are weird network issues... or people misconfiguring their devices by removing permissions/notifications from GrapheneOS system apps, disabling cert CAs, etc. The system is typically very good at maintaining itself if permitted to work in peace.
Please note that I do not speak for the GrapheneOS project.
