1) Apple is updating their Apple Push Notification root certificate March 29, 2021 AAACertificateServices in place of the old GeoTrust Global CA root certificate.
2) Also, Apple will no longer be suppporting their APNs legacy binary protocol after March 31, 2021 requiring an upgrade to the APNs provider API.
We are using Microsoft.Azure.NotificationHubs.dll (version 4.1.0.0) to submit Push Notification requests via Azure to APNs as well as GMC/FMC. We would like to know if Microsoft.Azure.NotificationHubs.dll will require an update to satisfy either of the two upcomming events in March or if anyone has any information about this at all. It seems to me Microsoft.Azure.NotificationHubs.dll will need to be rev'ed to handle these...but we are unsure.
