Hi ASDAccounts,
I get that you're having trouble with the recurring sale order not saving after changing the customer name. That can be really annoying. I tried it out myself and was able to save the recurring invoice with the new changes, so it's strange that it's not working for you.
Please clear your AccountRight cache first. Sometimes, clearing the cache can fix weird issues like this. If that doesn't work, you might need to recreate the recurring transactions from scratch.
Feel free to get in touch if you need more help.
Cheers,
Princess
