Support confirmed that the QuickBooks app will not work on iOS 18.7 on the iPhone 13 Pro. Can you provide a full list of which iOS versions are incompatible with which iPhone models?

This information should be readily available to users so they can avoid updating to a version that breaks compatibility — or worse, purchasing a phone that won’t work with QuickBooks at all. I was also told that iOS 26 will not work, and that QuickBooks will not function on the iPhone 17.

If there are known incompatibilities, they should be published and easy to find. This is software development 101 — transparency on supported devices and operating systems is critical. Failing to do so creates major problems for long-time customers like me.

As it stands, I now have to rely on an old iPhone XS Max tethered to my work iPhone just to run QuickBooks in the field. I’m about to upgrade that XS Max to iOS 18.7, but I’m taking a gamble because there’s no official information about what devices and iOS versions are supported.
