At least you got a reason from Google. I have an update to an iOS app that's been stuck in review for two weeks now with zero feedback from Apple other than boilerplate responses from support. This is causing me serious stress as I have no idea how long it's going to be in this state and I rely on this and another app for 100% of my income.
I re-built it with a newer version of Xcode, bumped the version the number, resubmitted. It was approved the next day.
