I'm looking through old Assistant threads but they either can't be loaded or can't even be found.
Here's an example thread which shows up in my thread searches, but when I click on it the Assistant says "This thread doesn't exist or you don't have access to it.".

I have the Assistant set to save threads forever, and anyway this thread shows up in my search results so I know Kagi has in.
If I go to my sidebar and click on Public threads (with a count of '4'), the sidebar doesn't show any entries.

The Temporary threads panel also doesn't show any data:

I've tried from two different devices.
There's definitely something going on here.
My old data is still accessible.
