Can't get latest Mac Nightly anymore

I run the Mac Nightly and have been downloading nightlies successfully every day for months.

Since the 31st January 2024 I haven't received another nightly update, despite checking every day.

My version is currently at 8.10.26-18, yet the beta page here say's it's up to 8.10.26-21 as of 7th February 2024, so I'm behind a few releases.

I even tried re-downloading the Nightly installer and updating that way, but it still left me with v8.10.26-18

I've tried toggling between the beta and nightly channels in the app, but to no avail.

Any idea why I can't update to the latest nightly anymore?
