Hello there, aj5string.
We have an ongoing investigation about unable to create trips when using the QBSE mobile app. This is already investigated by our engineers and working for a fix. Temporarily, you can use a mobile browser (Desktop mode) or a computer browser.
If you're already using a browser to access QBSE, I'd recommend contacting our Customer Care Team. They can pull up your account and review the details. You can reach them through this link: Contact QuickBooks Self-Employed Support.
We appreciate your patience as we work on this.
