Best Practices
Instagram Automation Tips:

✅ Mix content types: photos, carousels, Reels

✅ Monitor analytics weekly to optimize timing
Common Issues & Solutions
Issue: Instagram API Token Expired
Solution: Tokens expire every 60 days. Set up automatic token refresh or manually regenerate in Meta Developer Console.
Issue: Image Upload Fails
Solution: Ensure images are publicly accessible URLs. Use Google Drive with "Anyone with link can view" permission or cloud storage like Cloudinary.
Issue: Posts Not Publishing
Solution: Check workflow execution logs. Verify Instagram Business account is properly connected and has publishing permissions.
