Hi everyone, I was waiting for the update too, but I think I found a work around for the time being.
If you have the plugin Conditional Widgets installed and set each filelist widget up with it, they magically work.
I can’t see the reason, but it works. I got three filelists displaying files from different categories on the same page in the same sidebar right now. All are working. That is enough for me at the moment.
Maybe it’ll help.
