Strange filtering issue once published

I am bumping up against something weird I am hoping someone has seen before.

The two pictures below are from the exact same file and dataset. One (the top one) is shown in Desktop, the other published an viewed in Service (a browser).

The published one (on the bottom) is successfully refreshing. No errors. FIlters are exactly the same (date range set via New Filter Experience). Zero files changes between the two, but as you can see the published one cuts off the last two months. Again, there are NO errors, it just behaves like the dataset has nothing after OCtober 31st, which is not the case because the Desktop is pulling from the exaxt same remote source. Not a copy of it, but the same actual source.

This is happening across this entire report, so it's like there's a higher-level filter (just on this report) that I cannot find. Have you ever seen a report act like it’s filtered differently or missing data once it’s published (but works OK in Desktop)?
