Good Morning @DZomorrodian 730ebc htps, and thanks for reaching out! Could you please share a video of the behavior you're seeing? I’ve tried to reproduce the issue on my end, but the completed "To-Do" items appear to remain in the "All To Do" list after being marked as complete.
It would be helpful to see exactly what you're experiencing so I can better assist you.
Thanks!
Will make a quick video later but for now the screen I a referencing is below. The crossed out items do not leave this list as they did in the past.

Hey Dawn, I was able to simulate your user logon, re-crossed off the items, and they were immediately removed from the open "to-do" list. After reviewing, I believe this was a one-time issue, possibly due to caching or a refresh requirement. Please take a look and let me know if you experience any further problems.
Thanks!
Best,
Ashley
I am still experiencing this issue. Over the past few days I have crossed off a number of items and they do not disappear from the list. If I refresh it just removes the lines and puts the list back as all active.

Thanks for following up @DZomorrodian 730ebc htps! Can you please submit a ticket to our Support team for further troubleshooting of this issue?
Thanks!
Regards,
Ashley
