If you have taken the plunge to Magento 2.2.4 and you are running multiple stores within Magento you may have noticed a few issues, if not you should check your transactional emails for a start.
There’s a well known bug with Magento 2.2.4 whereby it ignores your email sender values for store views if you use different values per view.
There is one way to get around this issue and that’s too use the different store email address options. If you go to Stores > Configuration > General > Store Email Addresses and then populate one Contact for each store (hopefully you don’t have more than 5 stores). Once you have done that go to Sales > Sales Emails and change the Sender for the different store views.
