Dear Sir / Madam,
Do you also have the same issue?
When using the old experience, the Left hand side menu, shows normally as I set up in Navigation setting.
However, when change to new experience, a tab "Page not found" appears (circle in blue)
and there are more link than before (circle in red)
Why this happening?
Could anybody answer my question?
if this is a bug, could this be solved immediate?
Besides, some of my colleagues are using new experience, even the site admin force using new experience, I am still using old one? Why? Could anybody answer?
