I just noticed that the cartridge I last used yesterday is listed as last used 11/02/2022 on the Dashboard, though opening its details and looking under print history I can see all recent prints, including the one from yesterday.
This seams like a traditional caching issue where last used property isn’t invalidated when new data is coming in, but maybe on a TTL?
Anyhow, should be easy enough for the right developer to find and fix.
( and yes, I did clear my web browser cache )
