OneNote - Poor Distribution of Class Workbooks

[stumot]

Afternoon All, Over the past year some of our staff have been using OneNote to send students work, at one point they were using the Office 2021 version but found that clunky so switched to the Built in Windows 10 App version, however lately they inform me that the distribution from their teacher PCs to the Students has been patchy, some kids get the workbook, some don't or some receive it way after the lesson is over, I have done some basic troubleshooting (reinstalling the app, re-imaging the pc etc) but its not helped, I have looked online and the consensus seems to be that distribution through the app is hit and miss in general, I just wanted to ask if this was anyone else's experience at all?Please let me know Cheers
