i'm having trouble exporting to ios using the official export template, i've followed the documentation and added all the required data but once it finishes exporting some files are missing, specifically the .ipa, .xarchive, .xcodeproj, .log and .plist files, i'm using ubuntu16 and have already tried earlier versions and filling the unrequired export information but it's not working on my project or the demo ones, any ideas on why this could be happening?
