Hi there — we’re resolving some issues with the build machines as we speak. 40 minute delays to process a build are certainly not normal, but can happen under extremely heavy load or if the build servers in a bad state.
[edit]
ps if you’re comfortable with the iOS / Android toolchains, you can also do the build entirely on your machine! (If you’re not, we’ll have the build servers back to normal again ASAP.)
iOS builds are currently being processed more slowly than usual. We are looking into speeding up the builders today and we’ll post updates here: https://expo.statuspage.io/
