Could you please provide guidance on the following points:
- Start Token Throttling
- Are there any throttling limits or rate restrictions applied to Start Tokens?
- Token Invalidation Scenarios
- Under what specific conditions can a Start Token become invalidated?
- Are there known scenarios that trigger invalidation?
- Token Regeneration Timeline
- Once a Start Token is invalidated, how long does it typically take before a new token can be successfully generated and validated?
- Frequency of Invalidation
- Is there any documented or expected frequency with which Start Tokens may become invalid, assuming a normal development workflow?
- Impact on Push Notification Token
- When a live activity Start Token becomes invalid, does this also cause APNs Push Notification Tokens to be invalidated or refreshed automatically?
