You're right, the support team is very friendly and supportive. But my resolution times for recent issues have been 24-hour turnarounds, even when we were feeling some level of pain and labeled it "high". In this instance, which was definitely an "urgent", I just didn't have any confidence the issue would be resolved in time. Thankfully when we've had issues like this (mostly with development/staging environments) it's always easy enough to just spin up another app. But that doesn't make me very comfortable having my production stuff there.
