Feature Management for Mobile #1042
Description
Activity
Hi, MichaelLHerman Thanks for reaching out.
May I know the programing language of the Feature Management library you are using? Are you using targeting feature filter?
It would be helpful if we could segment wether a feature is enabled based on user OS (Android vs iOS) and based on application version (to turn on a feature only after a specific version). We are already using groups to segment users by client organization, so we can't reuse groups as far as I know, unless a user could be in multiple groups ("ClientX", "Android", "1.0.2")
Currently, you can use a custom feature filter to do this. A .NET example of custom feature filter which enables feature flag based on the browser type can be found here.
Another workaround is that you can give all users a version tag(group) and exclude all the versions before the specific version in the targeting filter settings.

Using ASP.NET backend which uses Microsoft.FeatureManagement, passing along a list of enabled features to the user in an API call upon login.Thanks, will look into a custom feature filter that parses a custom User-Agent string that will include app version and platform
Can you confirm that custom feature filters use an AND condition? If I have multiple custom feature filters on a feature flag, they must all evaluate to true for the feature to be on?
Edit: I see that a "Require all above feature filters to be enabled" checkbox appears when I add more than one, seems like the default is OR and checked represents AND. I think this could be added to the feature filter documentation you shared.
Reacted by Zhiyuan LiangHi MichaelLHerman you are correct it is OR by default. Checking the checkbox enables AND evaluation. You can check this document for more information: https://learn.microsoft.com/en-us/azure/azure-app-configuration/feature-management-dotnet-reference#requirement-type

We are using Feature Management for both web and mobile.
It would be helpful if we could segment wether a feature is enabled based on user OS (Android vs iOS) and based on application version (to turn on a feature only after a specific version). We are already using groups to segment users by client organization, so we can't reuse groups as far as I know, unless a user could be in multiple groups ("ClientX", "Android", "1.0.2")? Also support for version ranges would be good, as there'd be no way to do that in the current UI
