Openhab 3 AmazonEchoControl Slow PLAYER channel

Dear all,

i am using the AmazonEchonControl binding since several years and i am very happy about it.
But, since some time (cant say exactly since when) the response of the PLAYER channel is very slow (if even working).
In case i turn music on a echo show device i am getting a really delayed change in the PLAYER channel (PAUSE->PLAY).
Strange thing is, that other channels are super fast (for example last voice command).

As a workaround i tried to use the last voice command channel to detect playing music. But this didnt work…

I am using Openhab 3.4.2 on a RPI3b+ and AmazonEchonControl binding Version 3.4.2.

Does anyone have a similar problem or is it only me?
I am using German Amazon (Connected to: https://alexa.amazon.de).
