In my last SRE role I was the unfortunate victim of having to maintain a mobile app submitted to both the Android and iOS app stores. I would never wish it on my worst enemy. It was the one thing that I could absolutely _not_ guarantee any sort of reliability with. It was all up to the random person who happened to review the current release and the release process could be as quick as a day in the best circumstances or up to two weeks if we got a particularly difficult reviewer. They seem to have absolutely no context sharing between reviews.
