When the alert happened yesterday on my Android phone, my only thought was to stop the noise, so I swiped or tapped or whatever I needed to do to get rid of it. I did skim read it, so I know it was a warning about the wildfires, but any specific instructions would have completely passed me by, and I no longer seem to able to access the message.
Can you still access it on your phone? It's not important to me on this occasion, but it may be important for future alerts if there are instructions we need to follow.
