Could not Prefiltering On Today

It works well before ,but now it shows an Error on leftbottom area:
“Can’t upload a file to an asset without file”

plz help ,thx a lot

I am having the same issue, sent an email to support.
I am not getting the error you are getting, but I can’t prefilter.

Dave said they are looking into the prefiltered issue, not sure if this is the same issue you are running into.

Thank you very much! Now it works well
