Bose Soundtouch problems with >> Tag View

[mick3]

The command I used can be found by searching for "finding-a-shell-in-a-bose-soundtouch" (I do not want to add the link here).
In the telnet session of my bose speaker I entered: "ext list container 0$folders$f73$f81" and received the error message.

I have no problem paying a modest fee. But 38 GBP seems too expensive to me for the solution of my little problem. I will not use the streamer app or artist and folder images as listed under the additional options.

thank you for your quick response
