2 iMessage accounts into one iCloud account?
Is it possible to backup two iMessage accounts into one iCloud account?
I ask because we have several devices logged into one iCloud account. My wife's iPhone storage is filling up. I realized that iMessage on her phone wasn't set to store Messages in iCloud. I tried activating it, and got the following message:
Messages in iCloud is not available because iCloud and iMessage accounts are different.
All the other apps on her phone are using iCloud. Why not iMessages?
Also, when I accept the Ok prompt after getting the above message, I get the following message:
Upgrade your account security: To enable Messages in iCloud, review and upgrade your Apple ID security.
When I select the Continue prompt, it just goes back to the first message noted above.
