Your payment is only authorized when the seller processes the order, so the funds are not transferred right away to Bloop's account.
When a Seller cancels an order, we give your bank an order to void the payment, as the processing step didn't happen. After this order for voiding the payment, your bank may take some time to process the release of the funds and this may appear in your bank as "pending" or "unavailable funds". That lingering hold is not on our side, but rather a delay on the bank's end.
Is the captive state normal?
If this happens between 1-7 business days, yes, it's common, due to the normal banking behavior
If it happens for longer than 7 business days, this is not expected and you should contact your bank, as we cannot intervene directly. Bloop can provide the order's transaction reference number, if needed.
