You can easily do this yourself by going to Profile > Settings (gear icon in the top right corner) > Account Details and then to the line "Reset Account". There you will see a warning that your account will be completely reset and all existing data will be deleted.
​
If you decide to reset your account, simply click on the "Reset" button in the pop-up. Afterwards, you will be automatically logged out and your account will be deleted.
​
After that click "I already have an account" at the bottom of the home screen. You can then fill out the onboarding again. Use the same email address through which your subscription runs so that the newly created account remains connected to your subscription.
