You'll want to use a web browser to log in to your QuickBooks Self-Employed (QBSE) account, RLC22.
Since you're unable to access it using your phone, you can use a supported web browser on your computer. Sometimes, the app may not support the latest system updates or account features, which can prevent it from opening.
Please ensure that you are using the same login credentials when attempting to log in on your phone. Errors can occur due to slight differences in your email address, password, or capitalization.
As always, our Community forum is here to assist if you have further clarifications or concerns.
