Answer
Check in order:
- Routes selected — In My Follows → Transit, select at least one route with Delay alert on.
- Route actually abnormal — Normal status usually no push; delays, suspensions, etc. may appear in the message center.
- Same state not repeated — Same route + same abnormal state may be idempotent (not every minute); you may get a "recovered" message after restoration.
- Update delay — Data refreshes about every 5 minutes, not real-time.
- Message filter — In the message center, select the "My Follows" filter.
If the home page shows delay but the message center does not, that state may have been notified already.
