I think I'm probably at 9.1 or so, but I might be about 9.2. I use ethernet to connect to the internet and usually leave it unplugged unless I plug it in to check for software updates. I only use the Roku software to switch HDMI inputs (couple of Macs and an Apple TV 4K) or to Broadcast TV channels via antenna, or to adjust settings on the TV. Unless I can figure this out, I'll never buy another TCL TV (leaning toward an LG Nanocell 8). I'd really like to fix this, but have been looking at TVs from Cyber Monday and Black Friday.

I know others have seen this problem and I've tried all the methods I found to try and resolve the issue. Similarly, the Roku iOS app is no longer paired. I've tried all kinds of resets and unfortunately the remote is no longer paired with the TV because I put it into pairing mode while trying to troubleshoot the problem. There's no way to turn it off (or on) other than unplugging the power cable, or to get it into the main system menu. After about a minute or so, it reboots (goes black) into the same screen.
