Thanks for your comment and feedback. I'm not sure why you're seeing the "Todo Cloud Done updating" prompt often. Would you please send us a diagnostic log (this can be accessed in your settings) so that we can take a deeper look into what's going on. By sending the diagnostic report it will open a ticket with our support team and they can look deeper into the issue.
Updates to Mac and the web are planned in the future, but the timeline is TBD. We're wanting to ensure that we nail things correctly mobile first and take those learnings back to our other platforms. Thanks in advance for your patience.
Are you still experiencing this problem? If so, does updating to version 10.0.4 fix the issue for you?
