I'm having a mess with Astrid syncing with RTM. I marked an item as complete in Astrid. After it synced, several items that were due today disappeared in Astrid and now show up on the next occurrence date (they are repeating). However they still show up for today on the RTM web site.
I took another item due today and moved the date ahead by one week in Astrid. After syncing, it still shows up as due today on the RTM web site.
Is anyone using Atrid and syncing with RTM? How well does it work for you?
