Hi. We migrated our lists from wunderlist. We use shared list but now even we shared the lists that were previously shared, they do not sync, so other people don't see the completed items. If they assign a task, they can't see it completed. There are duplicate lists with the same name, one is shared, the other one is not. When creating new shared lists, the people who received the invitation are unable to join. they see an error "list unavailable" I tried support, but unavailable.
