iPad not sync with specific wifi
Installed new router and password. Successfully sync all devices including 2 iPhones and another iPad. One iPad will not sync. Recognizes network and even say wrong password (as a test). But with correct password will just cycle on it without sync. Will work with other networks. Tried reset network and hard reboot. The no sync iOS is 13.3 - the working iPad iOS is 12.4.4.
iPad Pro 12.9-inch, 3rd Gen, Wi-Fi
