Wearables Device Access Toolkit

IssueWorkaround
If there isn’t an internet connection present, your app may fail to connect with the Wearables Developer Access Toolkit, and you may not be able to register your app in developer mode.
An internet connection is required for registration.
Streams that are started with the glasses doffed are paused when they glasses are donned.
None at this time. You can unpause by tapping the side of your glasses.
DeviceStateSession (iOS) and DeviceSession (Android) are not reliable in combination with a camera stream session.
Avoid using DeviceStateSession (iOS) and DeviceSession (Android) at this time. Their omission will not affect camera functionality.
[iOS-only] Meta Ray-Ban Display glasses don’t play “Experience paused”/”Experience started” when pausing or resuming the session using captouch gestures.
This issue will be resolved in a future SDK release.

Wearables Developer Center

IssueWorkaround
Email addresses of members invited to a release channel must already be associated with a Meta account.
Verify anyone you invite to a release channel has set up a Meta account at meta.ai.
Users logged into developers.meta.com (Meta Horizon) may face an error with links from the Wearables Developer Center because it uses a different domain (developer.meta.com).
Logout from developers.meta.com before signing up for the Wearables Developer Center.
