I added the Attachments macro to a page. I uploaded a MS-Word document (204kb), but it does not appear in the Attachments macro table. But I see the document in my Activities feed.
I also tried to upload other documents, but they do not appear in the Attachments table or my activity feed. In all my attempts, I've tried both drag and drop and browsing for the files. I did not have issues a few months ago in late April (I use Confluence inconsistently).
The behavior for uploading files seems to be inconsistent.
