Cannot Access Insights and Print Designer on Frappe Cloud

I have installed insights and print designer on my frappe v15, erpnext v15 on frappe cloud but I cannot find these two apps. The url is showing an error “app not found”. How do I access frappe insights and print designer?

Can you post the traceback here?

I resolved the issue by uninstalling Print designer and insights then reinstall them again. Now I can access them. Thank you.
