I had to enable the admin tab, which I didn't know how to do. Luckily I found the config.json file in another thread.
Here's the log, though in looking at it, I don't know how useful it is. Activity button presses aren't being captured in the logging. I would expect that if I hit A, B, or C, that it would show in the log. I also don't see what commands are being sent to the TV, only button presses.
In order to get the button presses to show in the log, I had to have the remote connected to my laptop and hit refresh after. If I repro'd the issue without it being connected, then connected afterwards, I never got any logs.
Luckily this is a pretty easy repro and happens consistently. What's interesting is that when looking at the IR blaster via my phone, the A activity is sending a signal. The TV just isn't receiving it. I wonder if the remote is somehow sending a different command or something.
Also, if I start with activity B, power off, Hit C, then Power on, that works fine. It's only when going from B to A where I see this problem. So strange.
