Am I the only one having this glitch on Yahoo Answers?

There are a few reasons this might happen:

1. The answer was deleted by the user who posted it.

2. It was reported as a violation by enough users to get it removed from the display.

3. The spam filter has it (some mistakenly call it shadow banning, but it is not any form of banning) and only shows up for the user who posted it. An edit or few to the answer may get it to show up for others, but if the OP doesn't realize no one else can see it, they don't know they need to edit it (or ask about the issue to get the information about editing it). This happens to me often if I edit an answer (it will disappear from view for everyone but me, and many edits may or may not make it visible again).

If the Answer is not showing up then it may have been Deleted you may have to Pick a Different Answer as the Best Answer unless that Answer Ends up coming back Later on 

Yes, it's happening a lot on my questions.

Long-term glitch usually caused when the answer was posted from a cell phone. Only that person can fix it by editing the answer.
