Makes my phone hot – Oil Painting Color by Numbers Review

Downloaded this app about a week ago and love it, but it makes my phone really hot. Not like I have an old phone either (iPhone 8+) so I know that’s not the issue. I checked the date of the last update - only 6 days ago. If this keeps happening, I’m going to have to delete the app.
