Sync is stuck or messages are missing

Most "missing messages" are a gap waiting to be filled — here's how to check and re-run sync.

1 min read Updated July 14, 2026

If a chat looks incomplete or sync seems stalled, it’s usually a fillable gap rather than lost data.

The Sync page reports gaps and coverage so you can see what's missing.

What to do

  1. Open the Sync page and check the gap/coverage report (chats-with-gaps, empty chats).
  2. Re-run sync to fill detected gaps.
  3. Confirm the number is connected — sync needs an online session.
  4. Check your tier. Auto-sync, full history and search are Pro; on Free, messages are persisted but the in-app history view and search are locked (live-only). See Auto-sync on connect.

Tip. Identity changes (LID ↔ phone number) are resolved automatically, so messages reattach to the right contact after a sync.
