In order for your Strava rides to appear in Ride Spot, make sure your Activities Visibility is set to "Everyone". If your settings are set to "Followers" or "Only You", your rides will not upload to Ride Spot.
To view your privacy settings in Strava on the website, log into your account, click on your profile icon in the upper right, then click "Settings>Privacy Controls". Under "Activities", select "Everyone" and click "OK" to confirm.
To adjust your settings on the app, click on the gear icon in the upper right and follow the same steps:
One more thing to check in your settings is that your Map Visibility isn't turned off. If you opt to have all of your maps hidden from others completely, your activities will not upload to Ride Spot.
