What are potential issues with slot swaps?

Short answer: Warm-up issues: Apps may require time to initialize after swap. Configuration mismatches: If slot-specific settings are not marked correctly. Session state issues: If using in-memory session, it will reset. Traffic routing: Any in-progress requests may be affected briefly.
