Just try to Create an Account and get a fresh Nsec which can then Save to your Devices Security using the Passkey of the device (NIP K1)
Or log in using your existing Nsec via the QR Code Method ( must have Nsec QR code on another device)
If all else fails I can just drop an Nsec here from a Test account that you can use to try the app
There are also many How to Vids on our YouTube channel
