Quickbooks self-employed

Hello, I'm having trouble still connecting to quickbooks self-employed that I recently purchased 2 days ago. It's stating giving me an error code GraphQl error I recently spoke to someone about the issue. They told me to clear the cache if I'm using an android system and that did not work. I even tried logging into quickbooks using my mac computer and that did not work. I'm beginning to this it's an app issue or developer issue. I'm currently a uner driver and want use quickbooks self employed to track my mileage. I've already paid for the quickbooks self employed subscription through my Google play account however, I'm not able to access my account.
