67. what about updates?

68. App Store Complaint #23,493
Today, after 15 days, Ego version 1.4.2 was rejected due to an HIG violation. It was a
simple violation and I fixed and resubmitted immediately. While it’s frustrating to be
rejected, what makes this so much worse is that it took 15 days. That’s half a month.
Now that I’ve resubmitted I’m at the back of the line again, and it could easily take
another 15 days to be approved (or rejected yet again), which would make the process
for getting a simple bugfix point release approved and into customers’ hands take a full
month. That is absurd.
Here’s the note I sent back to the Apple App Review team, which I also CCd to the
Developer Technical Support team:
Follow-up: 83060940
I have modified the application and resubmitted. That said, I would like to say I’m
extremely frustrated by the fact that it took Apple 15 DAYS to reject my application and
now that I’ve resubmitted could take another 15 days to be approved.
That’s 30 days to get a bugfix build through, which is DESTROYING my business with
this application.
Please, I’m begging you, PLEASE don’t take another 15 days on this. My sales are
suffering and bad reviews are pouring in because I can’t get a bug fixed for my users.
This makes me look terrible. 30 days to approve a point release is insanity.
I’M BEGGING YOU.
Just when I start to get comfortable with the App Store again, shit like this happens. I
understand Apple is completely inundated with updates and applications, but that’s not
my problem. If you’re going to set up a system with this many requirements, you’d
damned well better be able to handle it efficiently. 30 days to approve a simple update is
not efficient.
