I was reading research papers, for literature review. Then after I read 10 papers, with each paper been highlighted (using the built in PREVIEW app, and highlighted with apple pencil pro), then after I was about to mark and select the paper I've read by using two fingers gesture. Suddenly after the selection action, all my highlighted papers were GONE. I thought that by doing the gesture, I accidentally moved or deleted the papers, but I search the file app for an hour, I didn't file a single paper that I've read and highlighted. I tried opening the PREVIEW app, since it got a history section where it shows the recently opened paper or pdf. Then I a pop up suddenly appeared when I opened one of the recent papers I've read, and it says, "The file can't open it doesn't exist or deleted". Unfortunately, due to frustration that I forgot to take a screenshot. I've lost hours and hours of my life reading those papers, but the bug of IPADOS liquidglass still a huge PROBLEM.

I have an airbrush connected to a continuous airflow compressor (Seleay AB900). I am planning to use this for my science fair project. I am planning to use this as a precise delivering insecticide sprayer. So, I want to calibrate it using an actuator or solenoid. Anyone know? For example, if the trigger was press around 50ms, the airbrush will spray around ± 0.5ml.
