I recently discovered the Acquisition > Campaigns > All Campaigns report is usually sampled in our Google Analytics. If I reduce the date range to 1 or 2 days, it might be unsampled, but even some single days are showing sampling.
I've gone through the GA page on sampling and nothing seems applicable. We do not have the Users and Active Users metrics enabled, it is not a Google Ads report, and it is not modified in any way from the default: I have no segments applied, have not changed the primary dimension or added a secondary dimension, have not clicked through on any entry, and have not filtered the table.
Everything I can find indicates this report should not be sampled regardless of date range. Is there another explanation I am missing?
