Not Syncing Between Computers
When accessing todoist from my home computer, tasks that have been marked completed persist. When accessing it from my work computer the tasks are marked complete. The only difference I can note is in the urls:
If I access todoist via https://en.todoist.com I get the correct results. If I access it via https://todoist.com I get the incorrect results.
Please log out of your Todoist account on all platforms/computers, clear your browsers' caches (and Todoist's offline data), reload the browsers and then make sure to always access Todoist via https://todoist.com and use this exact URL as a bookmark.
