Friends on Slopes work a bit differently than other social networks (by design!).
Adding a friend is still super simple, though, here's how:
- Go to the Friends tab in Slopes
- Tap on the "add friend" icon in the top right hand corner of the screen
- Your friend can scan the QR code, or you can send them a link via the iOS share sheet
If you choose to send the link, all your friend has to do is tap the link on their device where Slopes is installed, and confirm that they want to friend you.
