A user has notified me of a new bug: Switching to a bookmark causes the filter pane's filters to stop updating visuals throughout all pages. Slicers still update visuals as expected.
My user has this issue while on the web service, via Chrome. I've reproduced the same issue using my computer, in both Firefox and Edge. There is no difference between reading an edit mode. I've also tried another report and had the same problem. These reports has been in use for several months and this is the first time this has happened, so I suspect there is an issue with the Power BI service.
