8 out of 10 apps I have installed through the old store stopped working today, and I have no idea why. Auto updates were turned off in both stores, and they were only to allow updates via Wi-Fi, which I have not been in range of in about 36 hours or so. The icons disappeared from next to the name in the list of apps. It wasn't greyed out, the icon disappeared and nothing happens when you try to launch it. I was able to long press and reinstall. However, installing from old store causes it to fail again within a few hours. All apps installed from Beta store are still functioning. None of the apps installed from the old store are functioning any longer.
It seems to work installing from the Store Beta for the same apps, but it's a pain looking them up manually one at a time. However, for all the apps I have purchased, they now want me to pay for them again! ?!? Huh? Now THAT is what is broken with this store. I am able to find those apps as already purchased in my online account with Microsoft, yet when I install the app, it is a trial only and I have to pay or lose functionality I paid for or put up with the ads I paid to remove.
That's enough right there to make me want to revert. Until I hear this has been resolved, I don't even want to think about upgrading to Windows 10 for mobile. I paid good money for the apps, a lot of them over the last year and a half. I don't want to have to do that again. Only ONE app I downloaded that I paid for is still good. It's a free download where you pay your money directly to the publisher of the app to get enhanced features. I did that, and their servers still like me. Microsoft doesn't seem to care. This store situation needs fixing, badly.
