When the internet is realy slow, the app won't load the playlists, downloads, …
I think this behaviour is not optimal and that the local data should be loaded first then try to reach remote data.
I can reproduce this behaviour every day(on google pixel 6 and huwaei p30), and i can work around it by simply deactivating wifi and mobile data (not really a good solution), then data will be loaded from the local resources.
Thank you.
