Well, I did contact the reportapp@microsoft.com
:
Thank you for contacting us. For further assistance with the questions in Partner Center, please contact Developer Support here: http://aka.ms/storesupport and create a ticket there.
There was also attached screenshot showing "Non-Technical Support Dashboard" and "App Submission & Management".
So I followed that suggestion and opened a ticket. Below you can see the answer I received:
Hello Maciej,
Thank you for contacting Microsoft support. I see that you are having issues with completing your app submission. I see that you have a couple of different package validation errors. For your store policy violation, I see that you package violates the store policy 10.2.2. Please be advised your product must not attempt to fundamentally change or extend its described functionality or introduce features or functionality that are in violation of Store Policies through any form of dynamic inclusion of code. Your product should not, for example, download a remote script and subsequently execute that script in a manner that is not consistent with the described functionality. . If you are not sure how to implement these changes, I would suggest reaching out to our technical support team for help with correcting the errors in your app package. If you need additional help, please reach out to Technical support here: Services Hub (microsoft.com) visiting our technical forums is also helpful: https://social.msdn.microsoft.com/Forums/windowsapps/en-US/home?forum=wpdevelop. At this time, I will be archiving this service request.

The link "http://social.msdn.microsoft.com/Forums/windowsapps/en-US/home?forum=wpdevelop" is dead, but there is a link to this forum.
Actually, I still don't know what should I do. Any help is appreciated.
