Update fixes presence, invitations and user APIs in Link v207. See why native code and version matrix need to be retested.
Direct answer
Meta XR Platform SDK 207 reports that Group Presence is now working again in PC VR applications and Unity Play Mode when running with Meta Horizon Link v207 or later. Invitations, accessible destinations, and returning to other players have been restored, and several user APIs have stopped responding as unsupported. The version also started to return native error codes documented in several services. Because Link and SDK are updated separately, teams must register both versions and retest social flows, error handling, and compatibility before publishing.
SDK and Link form a combination
Updating only the library may keep the failure. Logs and reports must record SDK, Link, runtime, engine and tested build.
Presence is distributed state
Destination, sign-in capacity, friendship and app version need to agree. Tests should cover creation, invitation, acceptance, return and closure.
Correct codes can break old contours
Applications that handled incorrect code may change branches after correction. Remove workarounds only after reproducing each documented failure.
Unity Play Mode accelerates regression
Validating invites during development reduces the cost of the cycle, but acceptance must still include installed builds, different accounts, and actual network conditions.
Nexus Reading
Maintain a minimum version matrix and automate predictable states; Reserve multi-user sessions for latency, permission, reconnection, and failure experience.
FAQ
Does Group Presence work on PC VR with any Link?
The note requires Meta Horizon Link v207 or later.
Why retest error codes?
Version 207 now returns documented native code, which may change branches created for previous responses.
Play Mode replaces the installed test?
No. It speeds up development, but doesn't cover all account, distribution, network, and runtime configuration.
