Couldn't connect to REALM on Switch version.

I am playing Minecraft on Switch. After Nov 17's update, I cannot log in to my server in REALMS.

The system just say about " connection time out " and "The update of Realms will stand by in 48 hours." 

Does I really need to wait in 48 hours?

This problem are not just happen on me. I found some player in same situation with me.
