Oh dear. That’s not good.
I did some timings this morning.
It now takes about 3.5 minutes to start up. That increase though is almost certainly I believe due to the fact that I’ve since downloaded more music. As previously observed, there seems to be a correlation between this and the amount of downloaded material. It then took about a further minute to fully load 593 favourites and 469 items in the Offline Library. So overall, a slight improvement for me.
I haven’t had a reoccurrence of the downloading skipping tracks so far and I was able to download some missing tracks on releases without a problem.
Mind you, I haven’t tried to play any of these yet!
As I’m still trying to re-build my offline library after having it deleted by Qobuz, I still have WiFi on but once I’m up to date again, I’ll turn it off and see what happens.
