Problems With Embedded Comments

I’m having trouble leaving comments on some blogs with embedded comments. You know, the ones where readers can reply to individual comments. On some blogs, no problem. On others, I hit “publish” and my comment disappears with no acknowledgement from Blogger that I made it. I try again with the same result. What’s puzzling is that it isn’t consistent on all blogs with embedded comments. Anyway, if I usually comment on your blog and haven’t heard from me in awhile, that may be why. 

This is a known problem on Blogger that I thought they resolved. But I recently switched my own blog’s comments back to pop-up, after hearing from a regular reader who could no longer leave a comment when I used embedded comments. Is anyone else having trouble leaving comments on blogs?
