🔧 Troubleshooting

┌─────────────────────────────────────────────────────────────┐
│ PROBLEM: Build times too long (>30 min)                     │

│ SOLUTIONS:                                                   │
│ → Enable Library folder caching                             │
│ → Use self-hosted runners with SSDs                         │
│ → Parallelize platform builds                               │
│ → Split large asset bundles                                 │

│ SOLUTIONS:                                                   │
│ → Use test timeouts                                         │
│ → Isolate tests properly                                    │
│ → Add retry logic for network tests                         │
