LED won't turn off during sleep

I've recently performed the hack on my MCC and I'm quite pleased with the result. It certainly raises a few eyebrows, when the food processor streams the Australian Open or another current sports event. Thank you for providing your work Elias!

For about two or three days now, I've had the problem, that the led (around the rotary button) continuously flashes light red and white, when the the MCC enters standby/ sleep mode:

If I kill the MCC app (that usually causes the machine to go into sleep mode) and have it "put to sleep" via android settings (after 2 minutes e.g.) the led won't turn off either. Then it just stays plain white:

I'm not sure, what caused the issue to appear. I don't believe, there was an update to the MCC app. The installed version is "1.1.23-release" according to android's app info.

I'd appreciate any hints.
Take care!

I seem to have accidentally closed the issue. Sorry about that.
