To be able to manage two or more people, for example siblings, in a team with the same email address and password, you have to enter the exact same data when registering them.
The trainer sends you the invitation link -> you click on it -> select child #1 and register it with the desired e-mail address and password.
Then log out via "Profile" -> "Log out" and click on the invitation link again -> select child #2 and register it with the same data as for child #1.
You can then switch back and forth between the two via the club logo at the top center.
If you have already registered the two with different email addresses and passwords and want to use only one of the two logins in the future to be able to manage both at the same time, please send us an email to support@spielerplus.de.
Tell us the email addresses concerned and which of the two email addresses the people should run on in the future.
