I don't know either this is appropriate place to post this issue here or not.
I just bought a new Samsung A51 and restored all stuff from my previous phone using Smart Switch.
Finally, when i tried to restore WhatsApp messages, it says "Couldn't restore messages ", "Check your phone's internet connection and tap Retry to restore"
I have retried several times while connected with WiFi and Mobile data too but no success. I have also uninstalled WhatsApp and then installed latest version from Play Store but not succeeded.
Can anyone help on this?
