Crashes more often than it actually works. Nothing appears to be taken care of on the Dev's end because it has been going on for weeks now. Make one keystroke and it crashes. Give it 5 minutes, make another keystroke, crash. Seriously? So glad I didn't opt in for the upgrade. Texted on FBM for little bit for help, then been ignored for 3 weeks. Found another app that works on both computer and mobile device BETTER than this one. Libre seems to be working. Had for 4 days now no crashes.
