From my recent experiences it seems that an app submission can pass certification with no problems, but then a subsequent submission that only makes a very minor code change such as bug fix can fail certification. I accept that this will probably happen in general because full checks cannot be applied every time and different testers may pick up on different things.

However, it concerns me that one day I will run into the following hypothetical scenario:
I release a major app update which passes certification fine. I then notice a critical bug in the app which I need to fix as soon as possible. I release the bug-fixed version to the store, but it spends 3 days in certification and then fails certification. I then have to work out why it failed and make the necessary updates or etc and resubmit it for certification which could take another 3 days. That means it's taken me a week to deliver a critical bug fix, which could lose a lot of customers etc. Note that I have already experienced less serious versions of this scenario.

Therefore I would like to propose the ability to mark an app submission for an already-published app as a bug fix, which would either skip or fast-track manual certification (automatic certification using the Certification Kit would still be done). I realise this could be open to abuse, but perhaps there are some rules you could produce which a submission would have to obey in order to qualify - for example the app manifest should be unchanged except for the version number.

Thanks for considering this idea.

Please provide some consistency in the certification process. I submitted a game for publishing on Monday. It went through the entire process in about 2 hours. The game wasn't set to be published until Friday at Midnight.

Over the course of the week, some fixes were made to the game's code and was resubmitted for publication on Thursday around 10am.

It's been sitting in "Certification in Progress" now for 2 days. If it doesn't go through, I'm going to miss my published release date.

If you can't give a reasonable estimation on release times, maybe let us put multiple releases in the queue. That way, if the second one gets certified on time, it can take precedence over the previous version.

Please, give us the possibility to delete add-ons (with, without subscriptions etc) right in the Web GUI of the partner center.

Right now, if you want to delete an addon in the partner center (which you have created there), you have to:

Read and follow all the required manuals to delete an add-on with azure ad integration.

Create an account, wired app to it, get token, app-secret, tenantId etc.

Entered the needed ID also in the partner-center's section "product collections" and "adminstrator agreement".

Search desperatly for a complete c# uwp exambple how to connect and proceed with a follow up request.

Try to delete the addon finally via c# and deleteasync requests
Getting meaningless errors, because the above is so error prone and no complete example for uwp exists.

In the developer dashboard page there is the option to review and comment on costumer feedback. This is a very nice capability and thank you for providing it! Unfortunately, if the gives feedback on your application anonymously there is no option to comment on that feedback or change status etc. I understand if the comment is anonymous then they will not receive emails on my comments, but it would still be very nice to be able to comment on the feedback and track the status for my own use or for future customers to see if they are perusing previous feedback posts. So, can you allow us to comment and mark status on anonymous feedback please? Thanks!

For example, MS provide the lot of sdk and new technologies about Win10 Fall CU. The SDK itself support the side-by-side installation, then we can try the new API with our UWP Apps.

But, there are no way to distribute this kind of app to testers or customers that use Win10 Insider preview. It only allow the Customer Update SDK level.

I belive that Store should control the SDK level more grained.
You know, many of Microsoft Apps are updated with new SDK, and it'll be available at the store during Insider Preview. If our - ISV - UWP App also have this feature, we can spent more time to trying the new feature, and Insider customer and testers can use it, and we could got feedbacks.
