There has been a case that the onboarding checklist shows an empty message for a few sites, and I am not 100% sure what triggers that. It shows only the percentage of completion on opening the WordPress.com dashboard.
It looks as shown below.


In my case, I have completed all the checklist activities.
I can add the steps to reproduce when I figure that out.
There is an user report as well, from @katiebethbrown. #user-report
I have a user seeing this in 1580583-zen
All checklist activities are complete, but they see 89% Complete in the dashboard and the box cannot be dismissed.
Another #1610000-zen
Related to #26890 maybe?
Also in 1616802-zen . User's percentage shows exactly as in the bug report. As a note, we calculated that 91% is 10/11, so there may be a hidden/miscounted step.

It is very odd because for a couple of seconds it displays this screen before displaying the empty one with 91%:

Another report of this in 8659751-hc (followup in 1683236-zen)
Site: antheiart.com
Stats page shows 89% complete in an otherwise empty block that can't be dismissed, and the actual checklist is fully completed.

Hi there, I also encountered this in 9406793-hc (Follow-up in 1706788-zen).
I didn't see it when I first accessed the dashboard. It appeared when I refreshed the page, though. As with other reports, the user had completed the steps (8/8), but was unable to dismiss the graphic.

Also stuck at 89%
@Automattic/onboarding-dev, ping - as was previously mentioned here https://github.com/Automattic/wp-calypso/issues/30244

Here's an attempt to fix that issue. https://github.com/Automattic/wp-calypso/pull/30258
I haven't yet been able to replicate the 'stuck' incorrect percentage bug yet. I levelled my first accusation at the memoized function we use to grab the task list, but in all my tests it behaved :)
If you notice anything in common with these reports, be it the order of tasks completed, site theme, or anything else relevant, please leave a comment and I'll try to investigate further. 馃檱
I assume the bug @arunsathiya has reported is fixed with #30268. Let me know if it happens again.
It does seem to be resolved on production. Thank you, @taggon!
