New update new problems. Why do I need to be connected to the internet to play a DVD?
Edit 2: Issue Resolved. Per the suggestion by u/OlJommie I deleted the Blu-ray player and then reinstalled it. That seems to have fixed the issue with the Blu-ray player redirecting to the Microsoft store. The Blu-ray player app was 225 MB when I uninstalled it, but the freshly downloaded version is only 105 MB. Maybe a pile of updates upon updates was causing the Blu-ray player to do something it wasn't supposed to be doing.
Internet went down this morning so I decided to watch a DVD instead of streaming. I put the DVD in the disc tray and then on the console the Microsoft store opened "Check your connection. Microsoft store needs to be online. It looks like you're not." I thought okay that's weird, so I close the Microsoft store, open the apps menu and select Blu-ray Player. The Microsoft store opens again displaying the same error message. Restarted the console, play disc, and same error message. Why does The Xbox One now need an internet connection to play a DVD?
Game discs work fine it's just the DVDs that are having a problem.
Edit: After my ISP resolved the internet issue I tried playing the DVD again, this time connected to Xbox live. When inserting the disc Xbox will open the Microsoft store to give me the option to launch the already installed Blu-ray player. If I try to watch the Blu-ray player from the apps menu it seems to work fine. However if I go offline and then try to launch the Blu-ray player from the apps menu the console attempts to connect to the Microsoft store. So it would seem that the Xbox One now needs a connection to the internet to play DVDs.
