Question re: Aurender N20 Server, Qobuz album takes 10-15 seconds to start playing

When I select a Qobuz album. It takes 10-15 seconds for it to start playing. When playing the Blue Coast playlist and when switching from one track to another, I get the message “wait, reconnecting” (several second delay). 

All devices have been updated, rebooted, etc. I am working with Aurender Customer Support, and they remotely checked my Aurender N20. They report:

“The problem is not with the Aurender getting offline but most likely the iPad tablet communication reaching the Aurender with acceptable speed. If your Aurender does not say "No IP" on it, the network connection for the N20 is stable. Because the setup was stable before and as you said, had have not changed anything, it is most likely network related. This is Aurender’s opinion and what the Engineer has said”. 

When I get home, I will use my iPhone to connect to my N20 and see what happens. I will also check my iPad settings and will turn it off and on again (cold boot). 

Everything was working fine until several months ago. Assuming the issue is my Apple iPad (5 generation, 256gb), what should I be looking for? Maybe some Apple update changes some settings. Any suggestions or thoughts? 

I will also call Apple support for advice this afternoon. Thanks
