macos 26.2 did not fix the icon missing problem. I discovered that if you change the sidebar icon size in settings/appearance to large then the icon is ok and then if you set it to medium or small then is also ok. After another open the settings the icon is missing. If you leave sidebar icon size to large then is all ok. As soon as you change it to medium or small the icon is missing.
The thing is as I see, if you change the window size of the settings that you dont see the icloud icon then the icon is always there as you scroll down, but if you leave the windows setting size large that you always see the icloud icon then it is missed.
