Find Actions in a New Place and Get to Them in a New Way
Where: This change applies to the new Salesforce mobile app for iOS and Android in all editions, except Essentials and Database.com.
When: The new Salesforce mobile app is available the week of October 14, 2019.
Who: Available to users with the New Salesforce Mobile App user permission.
Why: The action bar shows the first three actions from the page layout, instead of the first four.
But if you’re on an iOS device and prefer using your thumbs, you can do that, too. Press and hold the navigation bar to highlight and expand the action bar. To scroll through the actions, swipe back and forth. To select an action, release your hold. To navigate away without making a selection, drag your finger off the navigation bar and release.
