When I post a new task, it is sometimes (more frequently lately) appearing twice on all my devices: my PC (where I'm using the Firefox add-on), on my iPhone, and on my iPad. The duplicate entry shows up immediately, and it's very annoying to have to scroll through a list of tasks and have several of them be repeats. I have tried logging out and back in, but that doesn't help. Whenever I see an App update for todoist, I update it. Whenever I see in the drop-down menu on my PC that a new version is available, I update it. Nothing helps. I pay for the premium service, so it bothers me that I am continuing to have this problem. Please let me know if you are working on this and when you expect to have it resolved. If I need to do something, please let me know what I need to do. Thanks.
