This only applies if you have OTP Enabled

If you start BDO Desktop, if you immediately start typing numbers, it will get bunched in the first box, and not auto-move to each consecutive box.
This seems to only occur when it first loads the Verification Screen, and not after a few seconds - So maybe its "Not Ready" before it accepts inputs.
I've replicated this a few times (For safety reasons these numbers are complete jargon)
