Once in a while, we update our Apps and Add-Ins via Microsoft. These updates are only necessary when we make manifest changes (a manifest is part of the application and distributed via AppSource or the Office store).Some customers experience difficulties updating the manifests distributed via AppSource or the Office store. In these cases, please create a support ticket with Microsoft as quickly as possible.Additionally, please send us (support@officeatwork.com) your information together with the Microsoft ticket number you received. We might be able to help or speed up the case for you.
