iCloud syncing

I use Agenda in both iPhone and iPad. But it seems there is late syncing time between them. I use cellular internet on the both devices.
I’ve recently seen an interesting problem in it: when I add a note to Agenda in one device, it syncs between the two devices very fast. But when I delete a note in one device, it does not sync and I see the deleted note in another device yet. Syncs after add, not sync or late sync after delete !!

We have a few fixes for sync coming. Perhaps that will help.
