We have 40+ apps on the App Store but as of yesterday one Mac App won't download.

When users download from the App Store the following error is displayed

We could not complete your purchase.

Failed to verify the preflight file. It is not signed by Apple.

All our other apps are OK and this app continue to work where it is installed (passes receipt verification and in app purchases still work/validate).

The app is Global VPN for Mac: https://itunes.apple.com/gb/app/global-vpn-free-subscription/id751048036?mt=12

Is this a new app or an update?

If an update, is it failing for both new purchases and updates?

I had the exact same issue on february 15 and 16 with one of my apps. I have removed my app from sale trying to understand and fix the issue.

In the meantime, as I my users and me are in panic mode😮, I have contacted apple developer support. They told me to open an incident. But no news yet.

So I have deleted my expired WWDR certificates in keychain and completely re-create distribution certificates and profiles and prepared an update to my app but now my receipt validation code (receigen) seems to fail...

In fact, it would be great to know if we are not alone with these issues 😕

Note: I have to check today that it still fails or not to download in purchased tab as one of my user told be it was resolved for him

The error "Failed to verify the preflight file. It is not signed by Apple." has disapeared since yesterday morning. No explanation. It seems an issue that Apple has fixed.

One user has reported this same issue to me, does it have anything to do with me? Or is it something strange happening on her computer? I did come across this:

But she says it's not helping her...

Update - I had another user just email me. Do I need to release another update after the worldwide dev relations ticket expired so that this is fixed?
