Welcome to the Fitbit community, @AEdeJager!

Sa to hear that you're having trouble using your Charge 5.
Sometimes it's a really good decision to start from scratch if your device isn't working as expected.
Please closely follow these steps to do so:

Hello @AEdeJager 

You should have your own Fitbit account, separate from your partner. You shouldn't be using the same account to log into Fitbit. 

Follow the instructions that @Talahthas  provided in the link. If you have any problems, let us know and we will do our best to help you get your Charge 5 setup.
