Zach has a Windows Lumia phone and he's heard that Chase is going to stop allowing access to his mobile app. Leo says that's because while the Windows phone OS is a great OS, there's simply not enough people using it to justify the effort. Banking apps have to announce and kill apps because of security issues. He may still be able to use online banking through the phone's browser, though.
What could change things is that Windows 10 will enable users to make cross-platform apps. And that could possibly save Windows phone -- but it's not looking good. The best technology doesn't automatically win. Leo also thinks that if sales don't pick up by the end of the year, Microsoft may just kill the Windows phone.
