What device are you using? I'm using a pixel, and for us there's a small arrow on the very top right side of the notification that will expand it to show the full text. Also swiping down on the notification itself will expand it too.
Yes, thanks for the reply. My phone is a Moto X4 android. Here is a screen shot in the horizontal mode which gives the most room for long lines. They still can be cut off. On your phone they seem to wrap. On mine they don't. This is not unique to the Tesla app. I thought there might be a way to read notifications in the app. I can't find a way to do that.
Wait, I figured it out. First the Tesla notices have to be unfurled to show them individually. Then any overlong notices can individually unfurled to show wrapped text instead of cut off.
I've had this phone for two years and it's still hiding secrets.
