Zero sec engagement session on analytics?

Hi, I've started getting smol traffic from pinterest suddenly. since 2 days. at first day it was like 30sec-2min session duration per user on the blog posts. But since yesterday i see 0sec to 4 sec and they are different posts too, not like same posts seen by same people and quick exit. Is this analytics glitch or does my content really suck?

Google analytics pulls out good data per my experience
But then ,zero second shows you didn't get any traffic, this should be true except something is wrong with the codes

its possile the pin went viral for a few seconds then dropped off

Possible but google analytics shows 0 secs session engagement mostly. So the users clicked the article and then closed it or exited. Is this normal for new Pinterest>blog sites with low initial traffics(<100 users ) Or depends entirely on contents?
