## Common Technical Issues & Solutions

### 1. Login and Authentication Issues

#### "Invalid credentials" error
**Symptoms**: User cannot log in, receives "Invalid email or password" message
**Common Causes**:
- Incorrect email/password combination
- Account locked due to multiple failed attempts
- Browser caching old session data

**Solutions**:
1. Verify email address (check for typos, extra spaces)
2. Try password reset flow
3. Clear browser cookies and cache
4. Try incognito/private browsing mode
5. Check if account is locked (wait 15 minutes or contact support)

#### Two-Factor Authentication (2FA) issues
**Symptoms**: 2FA code not working or not received
**Solutions**:
1. Ensure device clock is synchronized
2. Try generating a new code (codes expire every 30 seconds)
3. Check authenticator app is configured correctly
4. Use backup codes if available
5. Contact support to reset 2FA if backup codes exhausted

### 2. Performance Issues

#### Slow loading pages
**Symptoms**: Pages take >10 seconds to load, timeouts
**Troubleshooting Steps**:
1. Check internet connection speed (minimum 1 Mbps required)
2. Test on different networks (mobile data vs. Wi-Fi)
3. Clear browser cache and cookies
4. Disable browser extensions temporarily
5. Try different browser
6. Check TeamFlow status page: status.teamflow.com

#### Mobile app crashes
**Symptoms**: App closes unexpectedly, freezes during use
**Solutions**:
1. Force close and restart the app
2. Restart device
3. Update app to latest version
4. Clear app cache (Android) or offload/reinstall app (iOS)
5. Check available storage space (minimum 500MB recommended)
6. Report crash with device logs

### 3. API Integration Issues

#### 401 Unauthorized errors
**Diagnostic Steps**:
1. Verify API token is correct and not expired
2. Check token has required permissions
3. Ensure proper Authorization header format
4. Test with different API endpoints

#### 429 Rate limit exceeded
**Solutions**:
1. Implement exponential backoff in API calls
2. Check current rate limit status in response headers
3. Consider upgrading plan for higher limits
4. Cache responses when possible to reduce API calls

#### Webhook delivery failures
**Common Issues**:
- Endpoint URL not accessible from internet
- SSL certificate issues
- Timeout (webhook endpoint must respond within 10 seconds)
- Incorrect response status (must return 2xx status code)

### 4. File Upload Issues

#### "File too large" errors
**File Size Limits**:
- Basic Plan: 25MB per file
- Pro Plan: 100MB per file
- Enterprise Plan: 500MB per file

**Solutions**:
1. Compress files using zip/rar
2. Use cloud storage links for large files
3. Split large files into smaller chunks
4. Consider plan upgrade for larger limits

#### Unsupported file formats
**Supported Formats**: 
- Images: JPG, PNG, GIF, SVG, WebP
- Documents: PDF, DOC, DOCX, XLS, XLSX, PPT, PPTX
- Archives: ZIP, RAR, 7Z

### 5. Integration Problems

#### Slack integration not working
**Setup Requirements**:
1. Slack workspace admin permissions
2. TeamFlow Pro or Enterprise plan
3. Proper webhook configuration

**Troubleshooting**:
1. Verify Slack workspace URL is correct
2. Check webhook permissions in Slack admin
3. Test with simple message first
4. Ensure both apps are updated to latest versions

#### GitHub integration issues
**Common Problems**:
- Repository access permissions
- Webhook authentication failures
- Branch protection rules blocking commits

**Solutions**:
1. Verify GitHub personal access token has correct scopes
2. Check repository permissions for TeamFlow app
3. Review webhook logs in GitHub settings
4. Test with public repository first

## Browser-Specific Issues

### Chrome
- **File download issues**: Check download settings and blocked downloads
- **Extension conflicts**: Disable ad blockers and privacy extensions temporarily

### Safari
- **Cookie issues**: Enable cross-site tracking prevention exceptions
- **Local storage**: Ensure not in private browsing mode

### Firefox
- **Security settings**: Adjust strict enhanced tracking protection
- **Add-on conflicts**: Test in safe mode

## Server Infrastructure

- Verify request format matches API documentation

### Mobile Debugging
- iOS: Connect device to Xcode for detailed crash logs
- Android: Enable developer options and use ADB logcat
