Since Sunday night, I can no longer get my iPad to work with Messages, FaceTime, Find My
Since Sunday evening, all of a sudden, my iPad is acting up. Messages app says an error occurred and your account is signed out of iMessage. It has a sign-in box, I log-in and it then says it cannot reach the server. Internet connection is just fine. All software is up to date.
Similarly FaceTime will not log in. Find My is not listing my iPad among my other devices -- even on the iPad itself.
iMessage App and Settings-->Messages, only will allow attempts to retry logging in, but can never find the server. Without logging in, there is no ability to change anything else. (Similar with FaceTime.)
Other iCloud shared information -- e.g. Photos are there. Safari Favourites are there. My Mac shows that the iPad is also signed in to my AppleID, as it should.
My iPhone shares messages with my Mac and iPad. All is still fine on the Mac.
I have only one Apple ID and confirmed it is the one I am using on my devices.
Multiple restarts over several days was not effective. My Messages App icon keeps having an Exclamation Mark badge on it upon restart. It is always trying to sign in but cannot. Turning off/on iMessage on my iPhone does not affect the iPad. Logging out of my Apple ID on the iPad and back in again, brings up a message box on my iPad that that says messages in iCloud not available as iCloud and iMessage accounts do not match. (But I believe they do match, and I only have one AppleID, iCloud, etc.)
Appreciate any insights, as everything I have found on line either is not effective, or cannot be done, as I have limited ability to adjust any settings on iPad Messages/FaceTime, and Find My cannot see my iPad even when I search for it with my other devices (which are still all seen).
Thanks,
iPad (5th generation)
