An instructor called for help with an issue that (so far) I've not been able to find documentation for. The problem went away -- but I'd like to know if anyone can point me to official guidance on this.
Problem: Modules not showing in Navigation (student view)
Modules have an invisible icon next to them (instructor view)
Confirmed: Modules are in the navigation in Settings
Confirmed: Modules and all contents are published -- green check-mark icons everywhere.
Observation: Modules contain discussions and pages.
Solution (though I don't know why):
Added 'Pages' to the Navigation. Once that was done, modules started showing-up in navigation as well.
In my own test course -- I could not reproduce this issue. Very curious if anyone has experienced this or has any wisdom on it.
Thank you Stephanie! I appreciate the response.
I'll bring this up with our Canvas admins on campus here.
