Well, I was wrong.........the delay didn't help. Not sure what is going on. Have no other non-OEM smart remote to learn from (however that is done).
Later Tuesday, 7/28
I deleted the TV outta the remote again and added it back in because I was messing with the delays and got to a point I couldn't remove it. App is a little buggy I think. After adding the TV back in I recreated the Activity, but WATCH ROKU didn't show up, so I tried a custom one and it popped up the ROKU as an option. Changes made late so waited to test in the morning.

Everything turns on now, but the delays are not right. I've tried a couple different delay settings but I must have something wrong. Even though the TV is first is seems to come on second (at least it's powering on though) but since it really powers up second the TV doesn't know to switch to external speakers, Turn the AVR off and back on it switches the TV to external speakers. So I'll keep messing with the delays.
Don't know if a new receiver would help in any of that or not, something not communicating in the ARC, since the AVR is only ARC and not eARC? I was debating replacing it anyway, maybe with a refurb X3600H or X3700H, since it has this random speaker static thing going on. Plus last week it was shutting down for no reason, but after 2 factory resets and letting it be unplugged all night the power down has stopped (for now).
What I did find out is that the TV remote does turn on the AVR and control the ROKU, which is interesting. Only missing two options on the OEM TV remote. The Home button goes to the Apps Home on the TV vs when on the Harmony it goes to the Home page of the Roku. When listening to music I usually switch to Stereo, so I use the Harmony for that.
Another new weird thing is it seems to miss the initial pause on a video so I have to press pause twice. I know it does that on YouTube.
I'll play with the delays some more and see what happens.
