I think there's some confusion here.
The problem is not the sync-dial access across all devices. No, the problem is that -- at least for me - they are not syncing across all devices automatically, meaning that the dials are NOT updating with new additions.
Perhaps once every three or four months there will be a new "sync," or update on the speed dial information. But that's it.
Why is this?
It would be nice too if saved-pages on the speed dial could sync as well, at least the links. But the lack of regular speed-dial sync is a big problem.
