This situation is continuing using the latest update of Start11 on 6/27/25; system tray is not appearing on the taskbar.
Start10 was so easy to use. WTH is wrong with Start11 that things which worked fine on Start10 are problems now?
As was requested, are you running Win11 24H2? Or are you running 23H2 or older?
Also, are you running Start11 v1 (latest version is 1.55)? Or are you running Start11 v2 (latest version is 2.53)?
I have multiple Win11 24H2 systems running Start11, some with v1 and some with v2. No problems on any of them with system tray not appearing.
NOTE: do you have Start11 Settings -> Taskbar -> Let Start11 enhance the Windows taskbar ENABLED or DISABLED? Again, I have both of these configurations on my assorted Win11 machines, and again no problem with system tray not appearing.
Are you running any other 3rd-party products that can manipulate the Windows taskbar and/or notification area (e.g. Explorer Patcher)?
