Hey there, this is an issue that we are aware of - as indicated within our Known Issues thread::
In rare instances, some players are unable to press A/X, Y/△ to get past the welcome screen. There's an issue here that we'll need to resolve Post-Beta, but for now, we encourage you to use a different controller, to connect the controller directly to your console with a USB Cable, and to disconnect any headsets/additional USB or bluetooth devices, as we have found that this helps remove the problem.
I hope that these steps may help you in getting past that screen and getting you onto the Battlefield! -- A factory reset is definitely not required to fix this.
