I'm fairly new to app development and I uploaded a couple of instances of an app to closed testing in Google Play Console. The first reviews from Google went quite fast and was approved, but now it is over 4 hours since I uploaded the most recent APK for closed testing and it still says that it is under review. I think I published around 5 APKs today for closed testing. I was just wondering if this is common? How long does it usually take? Does it take longer for them to review if you upload more APKs in a short amount of time? If so, is there a way to avoid this kind of behaviour?
Best regards
The time of review can vary a lot. From an hour to a few days.
If one of your APK is in the queue for review and you upload another APK that overrides the first one (i.e. on the same track), the first APK will no longer be reviewed, only the last one will be reviewed and enters the queue again. So if you upload APKs faster than they can be reviewed, nothing gets published.
I would suggest not to publish so frequently. Use the internal test track rather than a closed track if you want to iterate quickly within the same day. There's no review time for this track so it will be much faster. Use a closed track for the first round of testing within the company, internal QA, etc., by uploading an APK only every few days.
