Today, in the way the system is designed, there is no way to change the label of the submit button on the application page when using Mobile Apply. If the client changes it using three tier language pack, it will change the wording for all "submit" buttons into the system.
SuccessFactors Recruiting Management (RCM) - All versions
Product Managment team has confirmed they will deploy a new string key specific for this button, RCM_MOBILEAPPLY_APPLY_BUTTON_LABEL. With this new key, the clients will be able to change the label just for this specific button.
The deployment date will be happening within 2018Q1 release (Feb-10th Preview, Apr-07th Production).
