| Issue | medium | ## Configure maximum timeout (Consumption) |
| Issue | high | ## Use isolated worker for new projects |
| Issue | medium | ## Configure Application Insights properly |
| Issue | medium | ## Check extension bundle (most common) |
| Issue | medium | ## Add warmup trigger to initialize your code |
