My fiancée and I are having a weird issue with the Eero app. I am running an iPhone 12 Pro, and the app works as I would expect it to. She is running an iPhone 13 mini, and the screen refreshes every few seconds. Also, the focus does not stay on the control she is wanting to select. Both of us are running the latest iOS 15 update, as well as the latest eero app. Is there a setting on her device that would cause this behavior? Thanks in advance for any help.
