I have been a paid user of Smart Launcher for over 5 years now. Our of the blue my home screen stopped working. I was unable to see any of my home icons. Double tap was gone. I tried to go into the settings and reset the launcher in hopes of solving the problem. Instead ended up with a prompt asking me to purchase the app even though it recognized me as a verified me pro licnese user. I love this launcher and hope to continue to be able and use it. I look forward to hearing from you guys.
