Item successfully listed but not getting confirmation email and not showing in inventory

Hi,
i have not been able to list any items for 48 hours now. I normally use my phone to list items, which are already in amazon catalogue so not a new items. Listing goes through as normal but i dont get a confirmation email and listing doesn’t appear in my inventory either. I have tried around 50 different EANs even ones i have had in my inventory before and deleted them. I have also tried using desktop instead of a phone, tried different browser, tried clearing cookies etc, nothing seems to be helping. i have also spoken to several amazon representatives but nobody seems to be able to help. EANs i am trying to list are not restricted or anything as i had that checked. Please help, this is really getting frustrating.
