It looks like I've "lost" all of my paid gsuite account emails prior to Oct 13rd if I look at "all mail" and Oct 5th if I look at "important" mail. My free account appears to be missing emails prior to May 10th if I look at "all mail" and Apr 2nd if I look at "important" mail. Searching for terms I know are included in tons of emails going back years returns even older results. Given that I can see older emails when filtering or searching, I'm hopeful none of the messages are actually gone, just unreferenced.
