If I try to change the date when adding an expense and save it, it keeps reverting back to today’s date.

Hello and Welcome to the Community, mx115 👋

The most likely cause of this is a cache issue, to fix this please clear the cache on the browser you're using and then fully close and re-open this before signing back into QuickBooks to record the expense. If this does not resolve please get back to us below and we'll take a closer look. 🧐

Thanks!
