Yeah, I’ve had that exact “everything looks normal except traffic is in the toilet” thing and it’s maddening. Honestly I wouldn’t trust GSC too much day to day right after an update. It can look like a disaster for a bit and then half of it was just Google being weird. I mean, That said, if it keeps sliding instead of flattening out, I’d start suspecting crawl/rendering stuff before blaming the content itself. Also, “same plugins” is a bit of a trap. One update and suddenly your cache or headers are behaving differently even if nothing *looks* broken. I’ve had that happen on a couple sites and it was annoying as hell because everything passed the eyeball test. If it were me I’d watch server logs and see if Googlebot’s still showing up normally. If it is, then I’d be less panicked. If not… yeah, then something’s off.
