Published again and now it works! Thanks for your help.

I did the preflight, version is 2015.7.

Would love to be included in the beta, have some of the same issues.

Not sure if this is related but I had the same issue on a windows machine. On export to article the file would be created but Indesign would crash. Problem went away after I rebooted the computer.

Its not really an error message, just text that says "Cannot connect to 2016 Midland Metal Check your connection then tap to refresh". I've tried on a variety of connections that I know are working and it still gives this message.

I believe so, on the collections page it says published.
