Note: You will need Administrator and Configurator access to enable Check-ins.
You can follow the steps below to enable check-ins on your account:
Go to Configuration > Reviews & Check-ins > Check-ins and switch on the setting "Check-ins". Plus "Users can set up their own check-ins" if needed.
Go to Configuration > Reviews & Check-ins > Workflows and switch on "2-stage: reviewee/reviewer - closed (check-ins)". Plus set "Default check-in workflow" to the same workflow.
Then go to the Administration Centre > Form design to mark your check-in form(s) as quick review form(s). This is what tells the system to show them on the 'Start a check-in' pop-up:
Note: If your account is using Review Groups, you will need to toggle on your check-in forms for each group they should be available for in the Administration Centre > Review Groups tab > Forms that can be used at any time.
