Full Upgrade Option: UNAVAILABLE! – Character Pad Review

Post-Update: Unchanged... 128GB Apple iPhone 6s running iOS v. 10.1, FYI ======== Got the app to use a THEREFORE symbol. The app REFUSES to let me purchase the $3.99 upgrade & INSISTS that I purchase a $1.99 upgrade. I'll purchase neither until: 1) I can actually Copy & Paste the THEREFORE symbol. 2) This purchase quandary is BOTH detailed & resolved. (What's included with each purchase & what specifically distinguishes the options, aside from the price?
