How do I resolve "Unexpected Error (-37100)" on the mobile app when I want to save expenses and capture receipt?

Hi benedict2,

Thank you for letting us know about the error you received, so we can help you resolve it.

Yes, the "Unexpected Error (-37100)" on mobile apps was reported last month, and we found out that it's triggered when the old GST code is used. The good thing is our engineers have already created a fix for it. All you need to do is update your QBO mobile app, and you should be able to create expenses without errors. However, it sounds like you're able to create expenses now. Can you please confirm it?

Please know that you can also sign in to your QBO company using a mobile browser in case there's an unusual behavior on the app. However, you'll want to report any issues to us here immediately so we can address them as soon as possible.

On the other hand, errors and unusual behaviors are sometimes caused by compatibility issues. I'm sharing this article which contains information about the recommended operating system's version and browser: QuickBooks Online access for mobile devices.

I'm just right here if you have any other concerns with about your QuickBooks app.

Thank you for the reply. 
I tried and run some tests on my side. Funny thing is if I used the old gst code of 7% it can get saved. But when I used the new gst code of 8% that’s when the error happened. 

I deleted and downloaded the app again from apple appstore, and tried to save using 7% and 8%. Nothing changed. Old code of 7% get saved but new code of 8% gets error code. 

I believe this is a system problem. I hope QBO can help to resolve this in the app.
