AT&T made a number of announcements today.  FirstNet Assist is an app available later this year to allow extended primary users to request priority uplift during an incident.   FirstNet Single-Sign-On will allow a user to logon with credentials once and have those credentials transferred to other apps on the device.   The other apps do need to be modified with a software development kit (SDK) for that to work, and no apps presently have done that.   But there are now about 60 apps in the FirstNet App Catalog and others in the pipeline.  There’s also an API in the development ecosystem which will allow apps to modify their own priority under certain circumstances.   I don’t have a lot more detail on these functions/features yet, but wanted you to know they have been announced.
