QB App has completely crashed.

Creating invoices is crucial for you and your business nowadays, @Rtpringle. It seems that you are unable to create one due to specific error. I will provide you with guidance on this.

For iOS:

1. In Settings, hit General.
2. Click iPhone storage and tap QuickBooks Self-Employed app.
3. After that, tick Offload to free up the storage without deleting the app's documents and data.

For Android:

1. From your phone Settings, go to Apps.
2. Find the QBSE app and select Storage.
3. If done, hit Clear cache or Clear app data.

Alternatively, you may use any supported browsers on your device and access your QBSE to continue making an invoice.
