You should've received an option on your initial startup of your start9 to write down *any* seed phrases 

If you do not have this, then I'm afraid you have lost access (for now) to those funds

I recommend reaching out to the start9 team on telegram to resolve your issue💜 

 Hey @Start9,

May you guide this user & help resolve this issue ?

Thanks
