Have you fixed it? If not the most obvious and simple fix (for me anyway) is to make sure you start the engine up correctly. This is my personal order of doing things: All fuel pumps to ON, APU to AVAIL, APU bleeds to ON, engine start to IGNITION, engine master switch 2 to ON, engine master switch 1 to ON. I'm aware people will come criticizing me saying in the A350 it doesn't matter which way you start the engines (1 then 2 or 2 then 1) but I have flown the Fenix for a while now so it's just second nature. I'm sure you have been starting your plane up correctly but when I get that message on any airbus, it just means I've forgotten to turn the fuel pumps on. It happens often for someone like me 😢

I haven't had this issue but it could be some circumstances you were under. Would you be able to upload a video of this issue (maybe from before you pushback to the first or second time the issue happens). Thanks!

You can also use the arrow buttons which I find easier but it's just a matter of opinion.

Hopefully you have already tried it, but if you haven't, make sure you clear your WASM folder (you will need to recalibrate your throttle and some other stuff), follow the guide here! Hope it helps!

I'm not 100% so don't quote me on this... iniBuilds hasn't released the A350 for MSFS2024 marketplace yet, and I doubt it will be available for 2024 via the marketplace (if you bought in 2020) until it has been officially released for 2024. If you can't wait, fill out the iniBuilds Order Transfer form https://forms.inibuilds.com/order-transfer and you might be able to transfer it over to your iniBuilds account and download it through iniManager. This will only work if you are on PC though. Hope this helps!

When you select the aircraft in the selection menu "Airbus A350-1000 | iniBuilds", click "Configure" and make sure you selected "A350-1000" not "A350-1000 (no cabin)". Same for the -900. It will affect performance but not by much.
