Can players in the same household both win prizes in arena open

I didn't have any luck with my searches.

I know one person can't qualify for day 2 more than once on separate accounts.

My partner and I both play magic I regularly compete in the arena opens and they said they were gunna do the same in the next one. Will this cause any issues if we both end up cashing? Since we share an IP address.

I sent the question to arena support and they just sent me the faq which didn't have the answer to my question.
