After upgrading Bambu Studio to v01.08.04.51 all my filament profiles disappeared. The AMS was attached, but it showed no filament colors, and I had to re-add them manually and re-calibrate. Not a serious issue, but I don’t know where else to report it.
Did you try logging out and back in again first? That will normally fix that issue.
Thank you for the tip. I will try that if it happens again.
