I have iOS 11 Developer Beta 4 installed on my iPhone 7+ and on my iPad Pro. I want to utilize the sync messages feature with iCloud. I was able to with my MacBookPro running High Sierra Beta. But on my two portable devices there is no "Messages on iCloud" toggle or "sync now" section in Settings/Messages. We go right from being able to toggle iMessage on or off to "Show Contact Photos"
Any help?
