I'm trying to diagnose an issue on my Android. See below for more background on the underlying issue. But what I want to ask you now is why I can't seem to find anything in my Android Chrome (version 71) related to Chrome's "tab discarding". (For background on tab discarding and page refreshes, see http://superuser.com/questions/1353931/how-can-i-get-chrome-to-stop-killing-my-tabs-in-the-background/1353940.) I want to see if tab discarding might be the cause of my problem, but it's hard to diagnose because I can't find the parts of Chrome relating to tab discarding.
In particular, there are supposed to be tab discarding-related flags at chrome://flags, but I can't find any. There's also supposed to be a tool for learning about tab discarding information, at chrome://discards, but Chrome says that's an invalid link. (These flags/features do appear on my desktop version of Chrome 71, though.) It makes me wonder if my Android build of Chrome even does tab discarding.
