Yes, vould be.
With ours, initially, both of my bids said pending. Later, I could update one...but not the other. A few days later, the one I could modify changed to ' expired'. A week or so after that, the 'pending ' one froze, I couldn't then change my bid...but it still said pending.AKept checking, and about 10 days later, I got the ' congratulations' email saying they had accepted our bid, and had been upgraded..
It is likely they are considering your 'frozen' bid, but looking at earlier posts- there are no guarantees until they actually charge your card and send the email! Keep checking, good luck !
