Address Verification Problem While Upgrading to Spotify Duo

My wife and I have been trying to upgrade to the Spotify Duo plan for quite some time, but we have had a lot of difficulties doing so. Despite the fact that we both live at the same address, I continue to have issues with the address verification process due to a recurring issue. It's discouraging to have to deal with this problem when there's no clear information or obvious solution in sight. I would be grateful if you could either shed some light on this situation or help us find a solution to the problem we are facing. I respectfully request that this matter be addressed and resolved as soon as possible.
