Deprecation: Map Viewer Classic Deprecation

As of Q1, 2025, Map Viewer Classic is no longer accessible.  I have a few WAB items on my AGOL account that I update monthly, and up until this month everything published and updated as expected.  However, this month I noticed I lost symbology on some line features that are attribute-driven.  I believe this was a function of the new map viewer, not classic, but it always worked in WAB.  Now that classic is unavailable, the WAB shows all black lines with no unique symbology.

Is there a workaround for this other than rebuilding in Experience Builder?  I understand it's inevitable, but right now my maps aren't working and I'd like to fix them first before setting up the rebuilds.

Map Viewer Classic is still accessible, they just 'hid' it a bit.

You now have to view the Map item details first, then the drop-down menu will have the Open in Map Viewer Classic option:
