Deleted contacts after deleting old email account
I recently deleted an old email account off the mail app. I haven’t used this work email since I left the job years ago. I only kept it in the mail app in vase I needed an old email. Mail suddenly kept popping up a window for settings every time I used the app, so I finally deleted it. Later that day I noticed basically all of my contacts from the last 5 years are no longer in my phone. I tried recovering from Icloud contacts recover. No luck. I’ve completely erased my phone twice now to 2 different back ups from before the erase. Its not putting those accounts, account settings or contacts back on phone. Whats the point of backing up your device if you can’t recover the data lost.
