My checklist items are showing as separate tasks in Toodledo and syncing to Informant that way
At this time Toodledo does not support the syncing of checklists. When a task with a checklist is synced from Informant the checklist items are converted to standalone tasks. These tasks are then synced back to Informant as new tasks.
To avoid this you will want to make sure that your tasks with checklists are not assigned to your Toodledo sync account.
