I would say it didn’t care too much about that backfilling setting.
But I don’t know what those percentages means, from what those has been counted I had only feel that translations go back that 365 days, but I don’t know that for sure.
I started AI-translations quite early, when you guys introduced it, and if that 419/4125 means 419 translated posts out of 4125 possible ones, counted from that 365 time period, then there hasn’t been any backfilling.
So I started scrolling down one category (BTW, PWA in iPad shows only 20 topics, I’ll start digging it soon to see if there is older topics translated or not.
edit
yeah, it looks like there hasn’t been any backfill job going, so you guys are good. That was another user error again
