voice control unavailable

[coldstart]

I sometimes use voice control for things like "play INXS" from my USB-stick which previously worked flawlessly.

Today upon pressing the voice control button I was surprised by a message which probably translates to:

"Voice control messages are presently unavailable and being prepared. Please try again at a later time."

This condition however prevails and I have no idea what I did "wrong" since it worked a few days ago
Any advice is greatly appreciated!

Somehow the problem has resolved itself and the voice commands are available once again.

On the search for a "soft reset" function (none found so far) I dabbled a bit in the hidden menu and on returning to the normal screen the voice control was back.

It is all a bit strange. I have found a similar thread in an other forum - alas without actual solution as well.

However that chap was smart enough to snap a picture of the (german) message:
