Could we get a master list of the Alexa devices that support APL? I just ordered (and am now returning) a Fire 7 tablet that did not support APL.
I'll throw my knowledge in:
YES - Fire TV Stick 2nd Generation - 2016 release
YES - Echo Show 5 - 1st Gen (I believe)
NO - Fire Tablet 7 9th generation - 2019 release
YES?** - Fire Tablet 8 HD 8th generation - 2018 release
** After enabling "show mode" on the Fire Tablet 8 HD, I was able to get my APL-laden skill to open. However, the screen remained completely blank (black). So I'm not sure APL actually works the way it's supposed to. The tablet also seemed to have much worse utterance accuracy in my very quick test. I really had to enunciate to get Alexa to do what I wanted.
Here's the doc on show mode and supported devices. https://www.amazon.com/gp/help/customer/display.html?nodeId=G3JEMFDNH3FPB4XS
Note that Fire Tablet 7 is NOT listed.
