I have a workaround to edit the billing address, gtobias.
I've checked our records to see if there's ongoing investigation, but found none. I've also tried this on my end, and I am able to save the changes.
As a workaround, you can edit the billing address on the customer's profile. Here's how:
- Go to the Sales tab and select Customers.
- Select the customer you need to edit the billing address.
- Click on Edit.
- On the pop-up, make the necessary changes. Then, Save.
Once done, create a new invoice. It should appear the updated billing address.
Please let me know if you have other concerns.
