Ugh I just want to do math – CALC Smart - Scientific Calculator & Converter + Review

I have used this calculator for a number of years. However the most recent update throws up a dialogue that I’m supposed to swipe down to close but it doesn’t close and now I can’t do any kind of math to save my life! ~~~~ I received a dev response email today. I can’t tell who is being lame here. iIs it Apple because I only received the email about the developer response today, Oct. 2018? Or is it the developer because they somehow backdated their response, which is dated the day after I posted this review. I suspect it’s both! And restarting the app I didn’t help! You had a bad update own it!
