We have Matomo on premise.
I found that NOT all page views are tracked by PIWIK. I keep visiting the site on different pages, I can see other users’ visits are tracked in PIWIK, but other users’ are not. For my visits, it was tracked on one day May 7, but not the other days May 17. It’s strange that it tracks some visits, but not other. .
Is this a server site issue?
