No, it didn't seem to post. Don't worry about it, I copied the body of the review after the error appeared.

Did you by chance pick write a long review and post a snap too?

this may have been the issue, it now disables "post to snap" if you select "write longer review", try logging it again please with that in mind. @killerwot

Okay perfect, it worked. I just unchecked post to snap, so I'll remember that for the future.

Okay grand, so will I uncheck post to snap?
