Katharina and Tim were so delightfully weird.I'm not sure, I don't remember seeing one.
It's also possible that the public call-out of the Kazakh fed actually led to improvements for them. The original IG post has been deleted either way.
Interestingly, they're now training in Dortmund with Katharina Müller (Yes, Harley/Joker German Ice Dancer, Tim Dieck's past partner) and her coaches. They were previously with Zhulin.
