Yes, had a revelation about a change I made recently which WAS the root cause of my being locked out -- updated this post with that at the top. I had changed my phone to "network time" because it was showing people's texts who replied to my earlier texts, above them since the time had drifted. Related to this is that the Auth app would sometimes fail, and it seemed to be when it was at the very beginning of a minute, which drifted over time to me needing to type the digits right as the timer was ending -- and then, a second after the timer ended. So I should have put two and two together, earlier, but at least I wasn't locked out of any trades that I intended. Oh, just to be thorough -- the fix was in Settings in the Auth app, then "Time correction for codes" and all three exchanges now work. I was a little concerned that WEX wouldn't work, so even though I had logged into it on Chrome, I kept that logged in and loaded a Firefox tab, and tried logging in and it worked.

So, WEX must be a little bit more forgiving than the other exchanges. I wonder if that's, like, a server-side setting for Google Authenticator?

Nice action in Verge and Tron today! Been hodling those for over a month now, great to see! Still underwater but coming up for air! :)
