Lately the Notes app on my iPhone 7 Plus running iOS 13.4 doesn't default to the last note that was on the screen after closing it and opening it up. It seems to randomly pick a note and then that note is always shown when I open the app. Then after a few days another note becomes the default. I never used to have issues with this App until the last several updates. I've rebooted numerous times and completely turned the phone off, but it keeps doing this. Any suggestions...besides getting a new phone.
