Wont let me do anythink in the Mac.

Unfortunately I was using my Ipad to do all my work, Ipad was stolen , now I use my Iphone is a probelm cuz is to small, I had abour 50invoices 4 stimates, after creating the stimates I try just to do some cahnges in the Mac, and the stupid sofware keeps telling that i need to Upgrade, I send a lots of emmails to the “support team” they keep telling that I need to upgrade, this is a total BS not acceptable. I ask for refun and they just don’t answer, dont wast your time and money buy, spend a bit more and buy a beeter app.
