Qualified for platinum first time 24.12.2021 with 1,020 status credits, but not credited until 27.12.2021 - I assume due to Christmas break. Coincidentally we flew home on 27.12.2021 and earned 40 more status credits. This whole requalification year these 40 status points have counted toward requalification and in total I accumulated 803 status credits up to 30.09.2021. My account duly said, "great work you will requalify for platinum' (which was correct). Now after the last system upgrade, I have 763 status credits and with no further flying before 27.12.2022 so will not earn anymore. It appears the 40 status credits earned 27.12.2021 have now been lost towards requalification for this year. Two hours on the phone to two different agents and I have no confidence they understood me or will remedy the problem.
