Somewhat off-topic, but also a followup.. I'm worried I'll be "kicked out" of gmail as well, at least on my mobile gmail device.. an Android tablet. I have an old one which doesn't receive Android updates anymore, gmail works perfectly fine in Opera (and Vivaldi). I have a newer Android tablet, I bought it to be ready when the day came that the old one doesn't work for some reason, or an app won't work and can't be updated (due to too old Android - and in fact there are a few of those already).

The problem? The browsers work fine on everything on the new tablet, EXCEPT gmail. Whenever I try gmail, in Opera or Vivaldi (same versions as on the old tablet), I get something along the lines of "the site can't be found". As if wifi was off. (paraphrased, I don't have one in front of me). Been like that forever. It's baffling.
