In App upgrade does NOT WORK – Calculator 3.0 Review

I liked the features of the InApp purchase so I purchased the so called "Upgrade". However, after many attempts, iPhone and watch restarts I believe I could have used my valuable time better than trying repeatedly to load the Upgrade. Looking forward to using the "Upgrade" as soon as it loads or get my money back.
