APNs will no longer support the legacy binary protocol after March 31, 2021, which is used in TMMS for Enterprise. A Critical Patch will be released to upgrade APNs provider API.
For more details please refer to the article, Apple Developer: Updated APNs provider API deadline.
Impact on Server and Agent:
TMMS 9.8 which is using the full mode with Local Communication Server will have these issues after March 31, 2021:
All MDM features on iOS devices will not work (remote lock, remote wipe, MDM features in policy, etc).
There will be no impact to:
- All Android devices
- TMMS Security Scan Only mode
- TMMS full mode with Cloud Communication Server
Recommendation for Mitigation:
Upgrade the TMMS server to 9.8 SP5 Critical Patch Build 3128
We appreciate your patience as we are conducting this upgrade to avoid this issue.
