Hello @jrfoell, I have the same error, but can’t seem to reauthorize the API account. If If I enter the Client Id and secret and click Save Changes, WP doesn’t redirect me to Strava to authorize the API account. Instead the page is just refreshed and nothing happens. I have tried authorizing manually, but that doesn’t seem to fix the problem.
One thing I did notice, however, is that I can’t change the app name to a name that includes the word “Strava”, as instructed by the plugin, because Strava’s brand guidelines don’t allow this. Could this be the problem? Or is there anything else I can try?
