Previous forum posts indicate that you could long press on the group chat name and then edit. This is not an option. Did the most recent update change this feature?
Galaxy phones currently have two default messaging apps. Depending on your phone model, you either have Samsung Messages or Google Messages as your default messaging app. Both are available for all Galaxy phones.
This feature is possible in Google Messages, which is possibly your confusion in this matter.
Thanks for responding! You're unfortunately correct. It looks like the other posts I read were fake news. It's hard to believe such a simple organizational feature has not been implemented yet.
