Playing Play Lists on Google Home Mini

[wmt47]

Recently when I try to play a complete Play List on my Google Home Mini the Mini plays only one or two songs on the Play List and then stops.  I am quite sure it is a  Spotify problem because Pandora Playlists work fine

I have done a factory reset on the Mini's, reboot it, did complete reset up.  Spotify is my default music source on the Mini.

Any ideas would be appreciated

THIS ISSUE IS NOT FIXED. It not only is not fixed it is worse.  Now the playlist doesn't even get through the first song on the playlist AND at one point after saying "Hey Google, play Bill's Smooth Playlist" to the "Bedroom" Home Mini located in the bedroom the playlist started to play, played less then one song and quit BUT in the mean time my TV in the living room (which is attached to the Google Home app) started paying jazz ?  I think it was playing a Pandora station I have saved and was playing over the TV yesterday through the TV and its Pandora app???????   I had to go into the Home app and "STOP casting' to the TV.

I have the latest version of Google Home Mini app and my devices all have the latest Firmware Plus I ahve the latest version of Spotify.  What is going on????
