Navigraph navdata update not possible

[AceDuckling]

I'm running the MSFS 2024 SU4 beta, and since the new AIRAC has come out i have been unable to update it on the A350. The Navdata options bar shows "Cycle: null rnull" and I can download the new data but the download will always get stuck on 41.94/45.77MB, no matter what I do. I have tried clearing the WASM folder like 10 times now and reinstalled the 350 once as well, but nothing has helped. This is especially frustrating for me as I was planning to fly the CTL Vatsim event on Saturday in the 350, but without the proper navdata that'll be impossible.

I'm noticing the same thing. I've reinstalled, cleared the WASM folder, no joy.

I consulted with the official staff yesterday and was informed that you can choose SIM DEFIALT or wait for the next version(maybe 116 ? or SU5 ?) to fix this issue, or revert back to the previous SU version It's very frustrating, why not immediately take action to fix this problem?

Same issue here.

Same Issue for me aswell. Frustrating. What you can do for Saturday tho is updating the Sim default navdata via the Navigraph hub and then use the Sim Default in the A350. Should work until a hotfix is out.

I was not able to tell my plane that I have a valid navigraph subscription. Not entirely the same as here, but what worked for me: run MSFS2024 as administrator. 

And dont forget the possibility that it is simply due to the BETA. I dont think that you can expect that the ini A350 works totally flawless in a beta...

Know issues from SU4 beta. Some platform bug on the WASM side have been raised.

See the developers response here.

You can use Sim default nav data as a workaround.
