traveller Thank you for your input. My experience with my previous phone, Pixel 5a was the same, and I figured that this would happen if I acted too quickly after receiving the notification. Two things worked for me; 1. tapping the notification itself, which would open the message using the Messages app and display it, 2. waiting for about 15 seconds or so before opening Messages app, then the new message would show there. The problems I have now never happened with my previous phone, which I was using the Owner, not a secondary user, and I am inclined to blame that. However, some people report that they don't have the issues I have, although they are using secondary user(s) on their phones similar to mine.
