Step 1: Check Your Chrome Extension
The Inbox Chrome extension is the engine that keeps your messages in sync. If it’s not working correctly, syncing may fail.
Quick Chrome Extension Checks:
Make sure the Inbox Chrome extension is installed from the Chrome Web Store.
Verify you’re logged into the correct X account when connecting.
Look for the Inbox floating icon on X.com.
- Missing icon? The extension may need reinstalling.
If messages aren’t syncing, try:
- Clicking the floating icon → selecting your account → clicking Link
- Disconnecting and reconnecting your X account in Linked Accounts
Step 2: Basic Browser Fixes
Sometimes the simplest fixes work best:
Close and reopen your browser completely.
Ensure the extension is installed and your account is linked.
For large inboxes, remember syncing may take hours, but small inboxes (<100 contacts) sync instantly.
Tip: Syncing happens in the cloud—you don’t need to keep your browser open.
Step 3: XChat PIN Issues
If you’re using XChat (encrypted messaging), you need to enter your XChat PIN for syncing to work. Without it, the system can’t retrieve your conversations.
Step 4: Sync Timing Expectations
Small inboxes (<100 contacts): sync instantly
Larger inboxes: may take several hours
Recent X encryption changes: may affect older messages, but new messages sync normally
Clear IndexedDB (Advanced Fix)
If syncing is still stuck, your browser’s local data may be causing the issue. Clearing IndexedDB gives the extension a fresh start.
When to Try This
Messages are stuck syncing
Extension is installed and linked, but nothing updates
You recently switched X accounts or reinstalled the extension
How to Clear IndexedDB (Chrome)
Open X.com
Right-click → Inspect
Go to the Application tab
In the left menu, open Storage → IndexedDB
Find entries related to Inbox / messaging
Right-click → Delete
Close DevTools and refresh the page
This only clears local browser data—your messages are safe.
