This is what I found...
If a Poster adds a video on his timeline, without any description , Follower will receive email and notification (upper right corner) that Poster added a video with wording like " Poster added timeline post with video. Looks good...
Then if a Follower click on search button and type posters name.. search result will display Posters icon and _bx_timeline_txt_sample_with_video wording next to it. Not good.
Now, if a Poster adds a video and types lets say "redlight runner" in description field of added video, but before submitting it... then submits it... everything is fine... email and bell notification AND search results will show Icon and wording like … added timeline post Redlight runner. This is even better.
Also, adding a video without description... shows Lang key...editing already posted video and adding description wont change wording, it will still show lang key in search results.
Maybe figuring out how to make description field mandatory so users have to type something would eliminate this issue.
