Share PowerApps with Office 365 Groups
Office 365 Groups (aka: "unified-groups") are becoming the "standard" share target in Office 365. You can share SharePoint content (files, list items, etc.) with an O365 Group. You can share Microsoft Stream content with an O365 Group. You can share a Flow with an O365 Group. You CANNOT, however, share a PowerApp with an O365 Group. This is a huge issue and greatly complicates our job of "selling" PowerApps as a solution.
For example, we've successfully convinced a LOT of our client groups that an O365 Group is a better solution than "just" a SharePoint site (most of these had sites/site collections in our SP2010 environment). Many of them latched onto Teams as well, and by an large, they've been off & running. Then, they want to build a PowerApp to make it easier for their people to enter or update data. Sure, they can build the app, and since the data is coming from the Team's (or Group's) SharePoint site, permissions is not a problem. However, the Team/Group members cannot actually RUN the PowerApp until it's been shared with them. Since PowerApps only allows sharing with individual users or AD security groups (NOT O365 Groups), they need to either share it with each Team/Group member individually OR they need to have IT create an AD security group and populate it with the Team/Group members. On top of that, as people in the Team/Group change, the owner of the App needs to then update the sharing or have IT update the AD security group. This goes exactly against the concept of Office 365 giving users an easy and coordinated way to manage their Teams/Groups and the apps and services provisioned to them.
