No acknowledgement after adding comment.
When adding a comment to a post, the little "loading" logo goes
around and around and seemingly never stops. But whenever I back
out and enter the post again, my reply is there.
It would be nice if after sending the reply one could get an instant
acknowledgement, something like, "Your comment has been entered.",
so we could proceed without further checking.
The constant updating symbol with no confirmation is a glitch we see in some browsers - especially Safari, but other Mac browsers appear to have it as well.
The proper function does give confirmation - by having your post appear on the page.
Thanks for your error report, it may help us track the bug down.
