Device name: Moto G5 S plus 

YouTube app > Library > my videos


Steps to reproduce:

(1)open YouTube app and click on Library and then click on My videos 
(2)Now you add one video ( example XYZ)  to any one Playlist ( example ABC ) 
(3)once done adding now repeat the same thing 
(4) here you will find out the BUG 
(5)I mean if you again try to add the same XYZ video to the same ABC playlist,app shows an error message as " there was a problem with network [400]"

Expected result: It must give notification as the video is already in the playlist 


Actual result: it shows notifications there was a problem with network [400]

I think for Google company this issue should be a major. Because there are so many experts you have. 

Thanks
