I have my own dev skill with an invocation name of 'listen up'. This has worked fine for several years but now it's being completely ignored infavour of what looks and sounds like an ad even in the developer console,
I try and launch my skill and I get this (Someone elses skill),"The skill, Listen Up: Hearing Challenge Game can help you with that. Did you want to enable it?" 
This hijacker has been disabled so how can that prompt and suggest? Is the prompt Amazon driven and nothing to do with the skill itself. I now can't even launch my own skill in the developer console unless I change the invocation words and yet I've been using my skill for over 5 years.
