Hi, @kasper_sommer-li. I'm here to assist you.
Can I ask for additional details or a screenshot of the date notification on your invoice? For now, you can change the default date format the QuickBooks Online (QBO) uses in your Accounts and settings to check if there are any changes.
Feel free to check out this resource as well if you have other QBO-related concerns: Self-help articles.
We'll be on the lookout for your reply to assist you better. Take care.
