I bought some refurbished Echo Show 5s for my beta testers, and because they were out of service for a while, some of them had APL max version below 1.3 which is the minimum for my skill.
I told my testers to update their Echo Shows and everything started working again, but I need to handle old APL devices more gracefully.
The problem is, I can't really test that because new Echo Shows are up to date out of the box, there's no way to downgrade (as far as I know) and refurbished ones update themselves quickly. I guess I could buy a refurbished one, hope it's out of date and then quickly unplug it before it has a chance to update. But that seems suboptimal.
How do I pretend I'm using an out-of-date APL device to test my skill so i can be sure I'm showing the user a "please update" message?
