A few questions about the Triode SPOTIFY Plugin for my SB2. (playlist slow!)

Hi,
I have been a happy user of the SqueezeBox2 (long may it survive) for more than 10 years. I am currently using the Triode Plugin (thank you) 2.3.8.

I have been using Spotify more and more and in particular trying to share playlists with my son and others. I have a few questions/problems

1. Recently I noticed that when I go to Home/MyApps/Spotify and select Playlist, it takes a long long long time to find my playlists. It used to be much faster ... almost instantaneous. Other functions such as Search or Library under Spotify are very fast.
--- Any idea what is going on here? Why the slow down? Is it a setting I need to change in my Spotify Account.?

2. Some of the items in my Spotify Playlist (eg, the Weekly Selections) do NOT appear in the LMS Playlists. Can someone explain this to me?

3. Is it possible to create a Playlist on my LMS in Spotify and have it sent over so it will appear on my Spotify Account App.

4. Is 2.3.8. the latest or is there a newer version and if so how do i get it?

Thanks to all for the help and particularly those who are writing the support software.

Larry
