'Edit collections' not working

I was now in Your Books -> Collection Manager trying to change what collections are applied for recommendations and connections (removing the ticks on this collection, adding them on that collection) but when I hit Save, it does nothing. And it certainly doesn't change those ticks.
Checked this already some hours ago, checking it now, no change.

May be part of a known problem: https://www.librarything.com/topic/368601

Can you make edits at this https://www.librarything.com/settings/collections page?

Ok, seems to be part of that problem (I looked at the more recent threads, but didn't see that one).
The collections page works, thanks for that.

Closing as a duplicate of https://www.librarything.com/topic/368601; hopefully we can get this one fixed sooner than later!
