Sign-in Issues
If Google sign-in does not complete, close the auth window and try again.
Ensure pop-ups are allowed for Chrome extension authentication.
If shown in the side panel, include the displayed Error number and Error code when reporting.
Highlights Not Appearing
Refresh the current tab and reopen the side panel.
Check that you are on a supported web page (http/https).
Verify your highlights filter scope (This page, This site, or All saved).
Save or Sync Problems
If creating a note fails, check the in-app Error number for tier limit or input issues.
For paid plans, reconnect account access if sync remains pending after retry.
Restart Chrome after extension updates to ensure background services reload cleanly.
