Update: I now have 2 Realms listed in MC. My original (expiring) Mojang/MC App bought one AND the Microsoft Store 'purchased' (also in MC when EXTENDING) one, which renews every 30 days.
Realms as a whole seems to be having severe issues, I can't even download my realm world and upload it to the new "forced" Microsoft Realm.
Some communication from Mojang/Microsoft would be nice.

I used the Extend option this morning. Setup a new recurring sub with the Microsoft Store.
But my Realm is still showing 3 days remaining. I did send a support ticket to Mojang Account Support.
Following, same issue.
Spoke too soon. Got home and it's not working. Only thing that's changed is my network access point!! Will try the beta. /sigh
My 1.2.3.6 version suddenly allowed me back in. I have not tried the beta build. Thank you for the fix.

I am fast reaching the conclusion that this is intentional.
I think the old subscription model (manually extend for 30 or 180 days) is gone/going in favour of the "opt out" auto renew subscription with the Microsoft Store directly. Mojang probably had no suitable way of enabling the 30/180 day sub through the MS Store, so it will just fizzle out as and when our Realms expire. Besides, IOS and Android have had auto-recurring subs for awhile now, the MC App and Microsoft were the last to enable it.
Could have done with some communication on this.
