Why always a delay to bring up Roon control (vs. Sonos App)


When I open a Sonos App it is almost immediately available to take commands, change playlists, etc.

When I open Roon (on iPhone or iPad) after not been actively using it, there is always a delay with a blank screen with the Roon icon animated. It takes 4-6 seconds I would say.

It is a big usability hit between using the native app. What is Roon doing in this time, I guess it is calling back to Roon Core, but in 99.9 % of the cases, Roon Core is still there.

I don’t know if this is a feature request? I don’t know if it is specific to Sonos end points, but I notice it because I am sometimes switching between Roon and Sonos apps.
