HI Ares123456789
Thank you for posting your question this community, Based on your description you would like to get Sort by function on your laptop.
According to your description, I suggest you can open settings > Options > turn off Legacy navigation panes in the upper right corner of your OneNote interface, this option may cause this issue.
At the same time, we have also tested it on our side, if we turned on this option, we may not see Sort By feature.
If the problem persists after trying the suggestion above, since you mentioned that you don’t experience the same issue in new version, and we have also tested it with new version, and this feature works fine on our side, so I suggest you update your OneNote for windows 10 to the latest version, try this operation
You can go to Microsoft Store to check if you can update your OneNote for Windows 10, If the Microsoft Store says that the OneNote for Windows 10 application is the latest version, can you check if your Windows operating system is updated to the latest version? Reference: Update Windows 10
Best Regards
Ethan
