Hi

Ibbidder has not been registering my bids on my Ibid page, BUT some bids have been made to Ebay and ebay reported I missed the items!
But they are NOT on my Ibid page.
Other bids I have made and ADDED have not been registered on Ibid and I have received no notification from Ebay even though I know my bid was well above the winning bid!
This is one item in question 121723836936

What is happening?

Not sure what you mean by "Ibid page", but I checked the item 121723836936 and I see you lost it because your snipe was too low.
Your snipe was 0.5, but the item ended at 0.55 which is higher than your snipe.
Why do you think you were well above? Please clarify.
