I had the same problem and have been mailing with the skywards team for a while. They wrote me, "Effective 22 January 2024, all members will no longer be able to pool Miles to their My Family account for transactions with Financial Points Exchange/Conversion partners. This is the reason why your transferred AMEX points is not pooled to the Family account."
I made screenshots of the Q&A page, showing them it's misleading. Today they sent me a mail, telling that they have updated their web page, however they refused to pool the miles to the family account.
"The same is updated on our website as below : Please check this link : https://www.emirates.com/ae/english/...amily-account/Can I contribute all the Miles I earn from Emirates Skywards partners to the My Family account?Yes, you can contribute up to 100% of the Miles you earn on flights with Emirates, flydubai and other airline partners, as well as the Miles you earn with our bank, hotel, car rental, retail and lifestyle partners. Only the Miles you’ve earned with financial conversion partners can’t be pooled into your My Family account.
Unfortunately we are unable to transfer Miles to the family group account."
unprofessional communication, very disappointing...
