I am having similar problems with my BA Executive Silver Status. I achieved Silver Status in mid-April 2022 and have made a number of bookings on BA, Finnair, and Qantas since then. Seat selection is showing for an additional charge. I rang the BA Executive Club at the weekend and was told that there was a known issue which would be resolved in three days. I've just checked and it is still trying to charge me for seat bookings on BA, Finnair and Qantas. I spent 2 hours on the phone to BA at the weekend. If this is a known issue, it doesn't seem to be easily resolved. The call centre tried removing my BA Exec number from my bookings and then added them again (only to still show bronze or ruby status). My Qantas booking is showing a ruby status rather than sapphire. I'm worried I won't be able to access the lounge on forthcoming flights and additional luggage privileges won't be recognised. Doesn't seem like this will be easily or quickly resolved.
