content: I downloaded this app after hearing good things about it. I had todoist and my subscription ended and I wanted to try this. I downloaded it and brought over all my lists from todoist. After entering everything I uninstallled todoist bad idea. I decided to upgrade ticktick to premium. Once I upgraded they asked me to sign in which I did. Upon signing in it deleted all the items I had in the app already. Contacted support. Havent heard back from then yet. What a way to thank me for upgrading.
