Something that folks may not be aware of, but when you set up routines in your current time zone, if you change time zones (with your phone, not with the actual Alexa device), the routines change to the new time zone. In other words, routines do not remain in the time zone in which your Alexa device resides, they change based on the location of your phone/Alexa app. As such, all routines need to be changed based on your new time zone (if you're traveling for example), which is a major inconvenience.
I would suggest that there be a setting created that "locks" the routines so they are fixed in the time zone in which they were created (where your Alexa device resides), so they don't change when your phone/Alexa app updates to new time zones.
If this is possible, I'd love to know how to do it!
