There is motion at your front door

Thank you for the suggestion. I use an iPhone 6, The software is up to date (iOS 12.4.7). I get messages all the time (Fit Bit, Lifetime, etc.). The messages are always displayed on the homepage, and they stay there until I clear them away. Only Ring sends me a message (e.g., “There is motion at your front door,” which displays momentarily and then clears itself from the homepage without any help from me. My phone senses the motion, rings and vibrates but the message is seen only momentarily. If I look at the RIng app I can see there was an event and the camera captures it. So, is it a phone issue or a Ring issue? Truthfully, I am a little hesitant to act on your suggestion without more assurance that it will work. But I will keep it in mind. P.S. 2 soft resets to my phone have not helped.
