Minecraft Realms server does not update after "48 Hour" period.

Originally noticed on 17Nov2020@1800 - Logging in to server produces "Count Not Connect: Outdated Server!
Realms Update Pending Within 48 Hours"

On 20Nov2020@1800 the same status message was still displayed on the realm for multiple users. I contacted the realm owner and they made sure their (Nintendo Switch) client was up to date. The realm was originally purchased through a Switch account, although the primary user clients are Win10 and XBox. 

As of 0800 on 21Nov2020 the realm still displays this message for all users. 

What can be done to get this playable? The realm is paid for, all clients are up to date, and it's been almost 96 hours.
