I’ve had this problem since I started using Roon in the summer of '21. I even opened a support thread on it in summer of '22. My Stuff > History always shows every track I play but Recent Listening frequently will only show partial totals (like 0-15 min when an entire 45-60 min album was listened to) and will stop listing albums and artists that I have just played. This all usually happens after I’ve been listening for a couple of hours. My Core is Ubuntu server 22.04.2 with the timezone set to my local time zone (US/Los Angeles) via timedatectl.
