I'm really lost here. I've been using the MSIX tool for 2 days repeated uploading to the store only to see my app installs fine then crashes at the start. There is a little tick box in MSIX that says 'specify your own certificate to sign with' I thought the MSIX tool did all that for me (that's why I was typing in my publisher id/details etc) or am I wrong. Am I REQUIRED to have a certificate in order to put it on the store? So why the 'option'?
If this is the case why isnt that made clear and why doesn't it fail to install/validate. Why do I have to waste an hour of my time with each upload etc before getting the bad news as a crash only once I've gone through all the trouble?
And, if this isn't the case then why does my app crash on the app store at start when it runs perfectly well in any other desktop environment? (Desktop/Steam/Testing)
