B. Diddy's, thank you very much! It worked! Also, thanks for putting me in the right forum. If I had not wanted to reset my preferences, would there be a way to tell where the Photo Editor app was already running?
When I try to use Photo Editor on my galaxy note 9, it says it is being used by another app and I need to stop it before I can use it in my note 9 gallery. I can't find the other app using it. Any ideas would be appreciated!!!
