When I look at Invoices in Office365 business center I see the outstanding amount column. Then I can click on it and press Ctrl+F1 and it opens this page: https://docs.microsoft.com/en-US/dynamics365/invoicing/index Which suggests that I down load an Apple or Google application. Well, me and our employees have Windows 10 phones. Is it now impossible to use Windows Phone with Office365 and invoices? Will it be impossible for ever? We have no plans to change phone types. Everyone loves their Lumia 950 devices.
