Hi and thanks for the reply. I don’t know how it is supposed to work but I did delete GT on both iPhone and iPad and I know that I have to install the theme again in this situation. But when i opened the app, only the native reminders lists were there. My smart lists were replaced with the default ones that are there when you install for the first time. All the other settings seemed to be ok though.
I have tried to delete - reinstall the app on the watch, no change. Then i tried to delete - reinstall on my iPhone, and re-start my iPhone and watch. No change. If i try to click right now on my watch, it tries to open the app for a brief second but then I’m back again on my watch face. The same if i try to open the app from the app-list on my watch.
