Thanks but I'm still stuck. I'm running out of ideas and I really don't want to point to AIR as the cause, but this is where I'm at: I can use AIR 28 and build my iOS app on Windows 10 using Flash Builder 4.7... then I can upload okay through App Loader (with yellow warning, not red errors blocking submission). However, it never appears in my builds via appstoreconnect. I know it uploads my AIR 28 build because if I create a new build with the same subversion number, it squawks as me about being a redundant build. Also, when I build with AIR 30 (see below) I never get that message because I can never successfully upload through App Loader. The build never appears in appstoreconnect but I do get an automated email from apple: We identified one or more issues with a recent delivery for your app, "Viva Learning Mobile". Please correct the following issues, then upload again. Missing Asset Catalog - Your app is missing the asset catalog file in 'Viva Learning Mobile.app'. For more information see http://help.apple.com/xcode/mac/current/#/dev10510b1f7. Though you are not required to fix the following issues, we wanted to make you aware of them: Certificate Expired - The signing certificate "CN=Apple Worldwide Developer Relations Certification Authority, OU=Apple Worldwide Developer Relations, O=Apple Inc., C=US" with serial number 25 used to sign Viva Learning Mobile.app has expired. Learn more (https://help.apple.com/xcode/mac/current/#/dev154b28f09). I understand that's been addressed in AIR 30. So, when I build with AIR 30, I'm back to where I was--this error right in App Loader (before it can even post to appstoreconnect): I have carefully created a different set of certificates and provisioning profiles and done all this on mac. I also looked at the link you provided regarding read/write... but that's all on the mac, and in the past I've been fine (and sort of fine now with AIR 28) and use win10 to build and sign and then just use the mac to use App Loader. Please try to answer my question: I can follow Apple's instructions for putting the latest WWDR Intermediate Certificate Expiration - Support - Apple Developer certificate on my machine (that was part of me trying to resolve this using only mac). But, how does that apply on Windows? I can download the AppleWWDRCA.cer... double click it to install (not sure which store I should use--my current user, or all users). I assume that after I do that, I need to make the signing request again etc. I'm concerned my certificate store is in some kind of state that's causing my problems. I would appreciate very much any comments on building/signing on Windows 10 and AIR 30. Thanks very much!
