Devices not syncing "well".
The word "well" is a key word here: Texts, voice memos, and emails are received on my Mac, iPad, and iPhone, but if I delete something on one device, I would expect it to be deleted on the others, but deleted items usually remain.
I said "usually" because one way I can get things to sync is to delete everything on all devices. (I am not one of those people who keep everything. Once I read it, it's history.) If I start from scratch and everything is cleared, a deleted item on one device will be deleted on the others, but after a few days, the deleted items remain.
Any ideas?
