Does your routine include an announcement that is supposed to play on the device that activated the routine? All my routines that include announcements have started doing the same thing.
When I look in My Activity it looks like Assistant thinks I said the text defined in the announcement and is trying to interpret it as a new command, instead of just saying the announcement. I opened a case with Google and they are looking into it.
Sweet! I'm happy to hear that the issue is now resolved, and thanks for keeping me in the loop. By the way, thanks to @JSchlackman for helping here.
Let me know if you still have questions and concerns otherwise, I'll be locking this thread after 24 hours.
