leovegas blackjack locked my withdrawal for “game round reconciliation”.

Just got a weird email after a blackjack run - says my withdrawal is locked for “game round reconciliation.” I’m not new to playing and cashing out but haven’t run into this term before. Looked up some bits and it sounds like when a hand maybe got stuck in the system or something, but the round finished fine on my end. The edge wasn’t massive but I was playing with a matched promo, so maybe that made their system twitchy.

Anyone else have their payout frozen for this before? Did you just wait it out, or is there something proactive to try? Never had a promo cashout flagged like this on blackjack before.
