Dobio sam odgovor i od autora aplikacije prognoza, odgovor je sa sajta answers.microsoft.com :
I'm just here because i am a Dev and two of my apps suffer from this error from time to time. Users don’t even know what to do and shell we think what they do as first and sometimes only step > rate and & review the app > 1 star with some text threatening the developer!!! Even if it not the devs fault.
I have found the fault and why it starts in the first place. Windows Phone app users which install an app have an store of their app purchases in their own Microsoft IDs so they can download apps later on other phones if they had it on this Microsoft ID (email) so far it’s clear, now comes the part where some of the apps get deleted!!! from the Microsoft IDs from users as they never been installed with their emails. This is why this bug comes and why it states above the error "Store error" with a bold font - it is clearly not a developer or apps fault in any way.
I already have issues with this from last year and let me explain in short my story with the Dev Support. I contacted them and get after dozens of emails a clear response that "...the Store can sometimes be buggy and mess things up, delete users stuff..." “this will fix on its own" (ß this one is really no help because it will fix if new users come and the old one abandon your app!) all this answers from a high representative of the Dev Support team. After it happened again and again i have email him again that this must stop, he advised me to send my users to this support link - (here is the part of the email
"Phone Support:
https://gethelp.live.com/en-us/Pages/default.aspx
- Advise them to choose "Apps + Store" in the dropdown then click "Contact Us" at the bottom"
So after this issue happened to me with my own app as i could not install it anymore i got to this support and without any surprise do you know what the Support guy told to me "you should contact the dev because it’s clearly an developer fault" hahahahah i must laugh again. It is really not a dev or app fault! This is just a Microsoft fault with which i am suffering threatening email since last year! Users call me a thief! and a cheater and i got over 50 bad reviews because of this and what does Microsoft do ?! Does anybody say sorry or something to help with the threatening’s and bad reviews I got?! NOBODY! But really today i am really p**** because i got an email where a users said "i know where you live i will find you because of this error, nobody steals my money you cheater and i will kill you" so WHY should i take this?!
This Store bug REALLY needs to be fixed as many other apps suffer from it too. In the meantime i have found Metrotube suffered from this bug last year, Angry Birds, myTube these days suffers too. My two apps also (Prognoza and WP Novosti). If its the devs fault, why Microsoft then don’t gives out an Statement with something the Dev should not do to cause this error?! No, because it’s not the devs fault, and it never was.
And the biggest part of this surreal situation the sales support guy tells me i should contact the developer support (the guys which told me in first place to contact this sales support) so nobody want to fix this issue and Developers as well as their apps Users are threatened like animals.
Just a side note to Microsoft, we devs pay 30% fee for our paid app purchases to you so we don’t just say this error needs an fix we demand it for a better business relation between you and the devs.
