IS there a maximum number of days that an app has to be reviewed before end of that period? In other words: if an app is posted, a review HAS TO HAPPEN before x days, is a rule (hopefully) or no?
Nobody outside the realm of the review team knows if there is such a system except that I doubt that there is.
Are we allowed to post many apps at once? I mean as a developer I can take time working in multiple apps, then suddenly deciding to publish them all, that is okay right? Are their limitation or expected "published flow" to have?
Yes, we are. Once I submitted two dozen software titles over several days back in 2011.
Once an app has been approved and published, will the waiting times for updates (new versions of the app) reviews smaller hopefully? or how was your experience? Is there a general rule you have seen?
Yes. The wait time for a software update for an existing app is generally a lot shorter.
