I know I’ve had an issue before of not seeing a message a buyer had left, as it was buried (I can’t remember what it was in relation to). I didn’t even think to check this for offers sent and declined. Thanks for the heads up.
Sorry I can’t help with resolving this issue. I’m not sure even logging a tech support help request would be worth it, either. In my experience, you either get the wrong answer, or told it will be passed on to the relevant team. Then nothing changes.
