My app seems to have updated recently and now the Strava route suggestions is not working.
It will not come up with any routes when I ask for hills, hard efforts, off road etc from my location even though it used to have dozens of suggested routes.
If you remove some of the filters, eg difficulty, it might come up with a supposedly hilly route that is pancake flat, and not starting anywhere near your location.
It really isn't fit for purpose at the moment, which is really frustrating as it is the main reason I pay for premium .
