Maybe tours gave me the impression they're less stable early on (say, April 2020), whereas logs tend to die less? I'm not blaming the software here, it could be my phone (Moto G5+). I haven't tried using tour on the app lately. I'll try it.
I think in the back of my mind, I wanted to have logs available in case I wanted to analyze them offline later, and I thought this way I'd have both the log and the nice tour view. I've never actually done that, but I might some day. I guess if Tour is as stable as logs, and I can get a log from a tour somehow, I'd have no reason for my default use case.
Tour mode on the app really may be fine. I'll try it. Thanks!
