The Reason why your Youtube #Shorts is not showing is because it passed the 60 second time frame. If your Youtube Shorts is 59 seconds long or over, Youtube adds an extra 1-2 seconds by default resulting in your Youtube Shorts becoming 1.01 or 1.02 or 61 or 62 seconds.

The Trick is to finalize your Youtube Shorts at MAX 58 Seconds before uploading.
