I think it's something new? About halfway through 2025 my Accor stays started posting incorrectly. The accommodation always posted correctly and quickly, but never any incidental spending (transport, meals, drinks etc).

I was reading something on Reddit that apparently the accommodation posts quickly as the nightly rate pre-tax is known and is the amount used for calculating reward and status points, then the hotel sends through to ALL the total bill incl incidentals and the reward and status points are supposed to be updated. However that update never actually occurs - my points statement always shows the correct accommodation only amount, then there's another entry for the same hotel that says "this stay is not eligible as there's already a posted stay for those dates". I've had to get every single stay manually updated where I've had non-accommodation charges on the bill. Don't bother doing this through Claim missing points, just do it through Live Chat or WhatsApp
