Forum Post: menu Insert=>Insert image/video/file doesn't work

When creating or replying to a post, the UI provides menu Insert=>Insert image/video/file.  That has changed for the worse since the Be Communities update in November/December 2022.

Previously, that menu popped a folder browser dialog.  One could browse to a file on the local computer, which would then be attached to the post.

No longer!  The folder browser doesn't appear.  There is simply a text box.  We have to guess what the file syntax should be, and as yet I haven't guessed correctly.
