Is "Printer Offline" a PrusaSlicer Problem?

My Prusa CORE One+ consistently shows "OFFLINE" in the Connect tab in Prusa Slicer (v2.9.4).  The printer thinks it's connected to Connect and "ONLINE."  The Prusa app shows the printer as connected to Connect and "ONLINE."  Prusa Slicer does not appear to be talking to the printer at all (wrong firmware version, not saving setting changes, e.g).  I've uninstalled and reinstalled Prusa Slicer several times, and the behavior does not change.  This Connect "OFFLINE" problem that so many people seem to be dealing with sure looks like a Slicer problem to me.  Is anyone else seeing the same thing?

This is a periodic problem that happens to everyone using PrusaConnect. The only work-around when the service is down is to either temporarily switch to PrusaLink or copy the g-code to USB drive.
