iPhone 6S Plus, PS3
iOS 14.4.1, PlayStation®3 System Software Update 4.87
This issue happens when shuffling liked songs, an album or a playlist (although I haven't tested it, I'm positive it happens on playlists too, because it appears to be a shuffle related issue) on the PS3. If I get an ad after a song finishes playing, the next song is skipped after the ad ends.
Let's say (as an example, as this is not a realistic shuffle scenario and Ariana's songs have no correlation to the issue) that my liked songs are shuffling and right now Positions by Ariana Grande is playing. The next song is 7 Rings and the one after that is Dangerous Woman. Positions ends and suddenly I get an ad. After the ad ends instead of 7 rings playing, Dangerous Woman starts playing. (this happens when I'm controlling the PS3 with my phone but I think it might happen when shuffling only on the console too)
This issue does not appear to happen when playing my liked songs, an album or playlists normally (non-shuffle) so it appear to be a shuffle issue.
