How should a Twitch-chat glasses app recover after disconnecting?
The host should follow Twitch's documented EventSub connection and reconnect behavior, then separately restore the wearable display. A healthy service connection and a healthy glasses connection are different states. Recovering one does not prove that the wearer has received the latest message.
Avoid duplicates and stale replay
Keep message identities so a reconnect does not display an already handled event twice. Restore the selected item or move to current chat according to an explicit policy. Replaying a large old backlog can be more confusing than reporting that messages arrived while the display was disconnected.
Test a phone-to-glasses interruption separately from an EventSub reconnect. That makes it easier to locate a missing message and verify that the interface shows current status instead of leaving the last visible line looking live indefinitely.
A requested reconnect differs from a lost connection
Twitch documents a reconnect message that supplies a new URL and transfers subscriptions through its reconnect flow. An unexpected lost connection instead requires connecting again and resubscribing; Twitch does not replay the events missed during that gap.
The glasses app should therefore distinguish “caught up with the messages our host retained” from “recovered everything Twitch sent.” A host-side queue can preserve events it received, but it cannot recreate events it never received.
