Check your tasks on your to-do list in the top right corner of the navigation bar. Use the drop-down to assign the task to one who can be assigned.
Assigning tasks can be done on the to-do list. This list can be found in Lytho's top navigation bar, next to the profile icon. On that list, you have the possibility to assign every single task to one other authorized user.
Opening a task in the to-do list will bring you to the module, assets, or publication of concern. From the asset or publication detail view it is also possible to assign a task (if required) to yourself or someone else.
