When I open a new note (Win+N or via the launcher) I get the message
We're sorry. OneNote is cleaning up from the last time it was open. Please wait.
After a while a new note is opened. This happens at every new note.
I found a workaround: to delete the contents of
C:\users\%userprofile%\appdata\local\temp. This fixes the issue once, that is at the next new note I have the error message again (and, again, the new note finally opens).
These operations are perfectly replicable (new note, error, clean Temp, new note starts ok, next new note has the error, clean up ... )
Is there a proper fix for this issue? I have the latest patches and the issue is present on the net for quite a long time already (at least since early 2015).
