You can import tasks from Wrike by clicking the "Import tasks" button on the top of your tasks or by right clicking on a task and selecting the "Import tasks" option.
Select then "Wrike" in the list of import options and click "Connect to Wrike".
You will be redirect to Wrike asking you to sign in (if you aren't already) and to give your permission for Planless to read your Wrike data.
Once done, you will be asked to select your Wrike's spaces you want to import. Select the spaces you want to import and continue.
If your Wrike spaces contain Team members assigned to tasks, it will be asked to you to match them to existing team members, create new ones or ignore them.
(Be aware that planless doesn't have multiple assignees per tasks. If you have a task with multiple assignees in Wrike we will import the first one of the list as the task assignee).
Once done, just select the destination of your import and finish your import.
