Error 9.0 on data transfer

I’ve tried to transfer my data from an older iPad to my new phone, but each time I click transfer data via EA account (The only one paired with the account). I get error 9.0 no matter of my WiFi or signal, and since the iPad is so old I can’t check or change any account info due to battery life issues. I’ve tried troubleshooting and uninstalling and reinstalling the game on my newer device but I’ve still had the issue. I’ve also contacted some EA support but they haven’t been able to reach a solution.
