You can change your profile name in the profile settings. To do this, go to your profile (person icon in the top left corner) and then click on the "Edit" button directly under your profile picture. Now you can edit your profile name in "Details" under "Name".
You can change your date of birth by opening your profile (person icon in top left corner) and then tapping on the settings (gear icon in top right corner). Under "App settings", select "My account" and tap on your date of birth. Now you can edit your date of birth in the app accordingly.
Important: You can only change your date of birth once in the app. A second modification can only be made by our customer care team.
