Route Import no longer working: RidewithGPS & Google Maps (Komoot OK)

One of the things I love about the Hammerhead dashboard is having so many options for plotting or importing routes -- given the limitations of each platform's mapping tool I often switch between them.

Unfortunately, since a few months ago I have been unable to ever get a Google Maps link to ever import successfully.  I just get a generic "Import error: Could not import this Google Maps route."  I wonder if something may have changed on Google's side, as my usual workaround (using Maps to GPX) has also led to a lot of errors with repeated slashes in the URL when using routes with a lot of waypoints.

Meanwhile, as of a couple weeks ago, RidewithGPS route import (which had previously been flawless for me) seemed to stop working.  I've disconnected and reconnected my account in the dashboard, to no avail.  I'm still able to import routes from Komoot, so I'm not sure if something is broken or if it's just something on my end.

Any help would be appreciated -- I miss being able to use all of the mapping tools at my disposal!
