Did a new build push this morning and it's working again. Not sure what happened yesterday, but I guess we'll never know.

We are having this issue here as well too. We have a group configured to get the latest builds added automatically and now it doesn't work. We are using Fastlane to automate the push, I validated that all ours credentials were ok and that's the case. I also see the build in the list, It just never get added automatically like usual to the group it should. Last time we pushed, 8 days ago, it worked properly, but not anymore.
