Listening to the live stream yesterday evening - they performed a significant amount of troubleshooting for the toilet. This required consulting with a full team of experts, including a "Toilet Lead". It seems it wasn't "flushing" waste into the collection bag or something similar - but they were eventually able to get it working.

I found the language NASA and the astronauts used to communicate absolutely hilarious - "Yes, we're excited and eager to begin immediate fluid disposal!"

Glad they got it working - best of luck to Atemis II mission!
