Check the connection
Check the internet connection and Lister’s sync status on both devices. Confirm that you are working in the intended group and that both devices or people have access to it.
Keep Lister open briefly on both devices and check whether a newly added change arrives.
Only certain items are affected
For a problem affecting one list, copying its items to a new list can help:
- Create a new list in the same group.
- Open the affected list and select all items from its menu.
- Copy the items to the new list.
- Check every participating device to confirm that the new list arrived in full.
Only delete the previous list after checking that everything was transferred.
