Mobile app new text indicator on the iphone OOMA icon

My OOMA mobile app icon (iPhone 12) shows 15 new text messages but when I open the app there are no new messages. I logged off and on still shows a little red “15” in the corner of the app icon. Open the app and it shows 15 on text message area. Open the texts, none are new or unread. Any ideas? I’m trying to not delete the app and reload.
