App Lab update on "Pending Release"

Hi all!

We currently have an app live in app lab for around two years. Normally, when pushing an update, the update is available within minutes of releasing, with the (metadata) check happening after. However, the most recent update we pushed is not yet live. This is an issue because the update is live on other platforms and because multiple platforms can collaborate we try to match the release dates as much as we can. Did anything change regarding the review process for updates for apps on app lab? And if so, how long can it take for an update to release?
