I need to build a Lightning App in an old org, and as a prerequisite, My Domain must be enabled.
However, there are couple things to take into consideration:
- Will the login change to My Domain login URL for all internal and external users?
- Will the URL instance for the My Domain stay the same for every release onwards?
I hope you guys can provide some more details since Salesforce documentation doesn't provide explicit information regarding this topics from what I've researched. Thanks a lot!
