Steps to replicate the issue (include links if applicable):

• look for a sequence uploaded after 11th April 2026, like HEnwoDN6lxdS7V4fqOv5PB or 2iJv5kIzrTcM8DAWB7Lbyx

What happens?:
The error message "Collection not found" appears. I don't know if Curator is able to retrieve more days after a sequence is uploaded, but I wanted to make sure the error is addressed.

What should have happened instead?:
A retrieval of the sequence with progress.
