Thanks, but I tried something similar w/o success. It's not officially supported, yet. See the linked site - coming later this year. It's been like that since June, I think.
I'm a Prime member, only have $40 invested in 2 Firesticks. I think I want to sell them and move to the Roku platform...
Looks like I need to throw away my Firesticks and switch to Youtube TV.
