In phase 1 of de escalation in cities, it is allowed to play padel 1 on 1. If you want this available in your venue, you will need to adapt the facilities (courts).
Browse to settings/facilities, click in the reference of the courts that you want to change to single. Scroll down to Facility features and here you edit the Court size, by changing it to single.
Important: this change will be updated online in the app an hour later when the facilities are synchronized.
Here is a quick video explaining how this is done.
