Filter pane not showing in app

I am with you!! It's insanely frustrating! The filter pane appears in the normal view of the report, but not in the app!! The thing is, on the report I'm looking at, the filter pane USED TO appear in the app, but then I kept uploading the report and updating the app in quick succession...which seems to have fritzed the App's ability to show the filter pane for the report (or something).

I have the latest version of Power BI Desktop, and even opened the report and re-saved it within Power BI Online, too.

This is definitely a bug that Microsoft's dev team needs to fix. But the moderators here are so greedy for their little green checkmarks that they rabidly mark questions as solved that aren't, so these issues just get ignored. (Does Microsoft even have a ticket system where you can reach somebody who actually has the power to FIX bug issues like this?)

Oh great...I just tried re-uploaidng the report, and now, in the Online editor for the report, the filter pane's "eye" symbol is crossed out. (Even though it wasn't when I published the report from PBI Desktop.) When I un-cross the eye (unhide it), and save the report, the changes don't actually save--So, the filter pane is now gone in both the App view AND the normal report view now...wow.
