Folks - minor update to a statement I made above:
Hi All,
Some more updates from Poly (Polycom).
1. We're working with Microsoft to push the new UCS builds (via Skype for Business Online Update) that incorporate the new App ID.
2. We have an official announcement coming hopefully by the end of this week. Refer to my blog in the interim for updates.
3. Initial testing suggests the users will not be logged out when the upgrade is completed, provided the consent is performed prior to roll-out and before the cut-off date. <- the latter is only true for users that signed-in locally on the device. For users that signed-in with Web Sign-in they will be logged out, this is due to the fact that their credentials are not cached on the device and so tokens cannot be renewed without intervention
I hope this helps!
