EPG empty and won‘t update

Channels I had to disable (I’m using Telekom Deutschland GmbH (Telco - Premium) - Digital as the provider):

415 Phoenix HD
056 ARD One
492 ZDFInfo HD
431 rbb Berlin HD

This might also be the right time to say that Kabel Deutschland (my actual provider) still has almost all channels missing in the digital listing. I’ve reported this many times but have yet to hear back from any dev.
