Sluggish with iPhone 13 pro max

I used this app with iPhone 10 and it was my favourite calculator app but since upgrade to iPhone 13 pro Max, the app not been working the way it should be. I would not use it till it gets upgrade and will not renew my subscription. After the screen get full with number it starts deleting the number backwords.
