In app – planned maintenance and unplanned downtime messaging

I'm designing the messaging for 2 types of scenarios. Planned maintenance, and unplanned downtime. in both cases, certain services on the app won't work, but the rest of the app will function as normal.

From the 2 options for planned maintenance, what would be the better options way to communicate these to users? Also, what should I consider when designing for unplanned downtime?
