Hello Afcoldwell, thanks for reaching out to the QuickBooks Community page. Are you using the QuickBooks IOS app to record the transactions? Is this when adding expenses that you are not able to add a category? If so, this is something which has been raised to our senior technicians, who are working on a fix right now, as it has impacted most of our IOS app users. For the moment if you could use the browser on your device to add the expenses while we resolve this. We'll add your company to those impacted and email you as soon as there is an update.
