Add to queue doesn't function quite right

I often browse my music, select an artist and say “Play Now.” I then continue browsing and find more artists, but I select “Add to queue.” For the first “Add to queue” this almost always results in a “Play Next”. However subsequent “Add to queues” typically work as expected.

For example:

AC/DC -> Play Now (this puts a bunch of songs in the queue)
ABBA -> Add to queue (this results in the first AC/DC song completing and ABBA starting to play)
Aerosmith ->Add to queue (this results in Aerosmith being added to the queue and playing as I would expect along with ABBA.
Air Supply -> Add to queue (this also results in Air Supply being added to the queue and playing as I would expect)

Can you take a look at ‘Explicit vs Implicit Queuing’ here https://support.plex.tv/hc/en-us/articles/202188298-Play-Queues and see if it matches your experience?

Does it behave differently in XB1 to the web application? Thanks!

So here’s a bit more information…

Queuing works exactly as expected at the Album level. However, it is definitely broken at the Artist level.

AC/DC - Back In Black -> Play Now
ABBA - Waterloo -> Add to Queue

Works exactly as expected First album plays then second.
