In the Summer ‘20 Salesforce release, Salesforce is retiring the Salesforce mobile web experience.
What does this mean for my users?
Phone (iPhone, Android) or Google tablet users using a mobile browser will get the aloha Salesforce experience.
These users will NOT have the option to change to Lightning.
These users will NOT have access to Lightning specific functionality.
If these users need Lightning specific functionality, they MUST use the Salesforce mobile app.
iPad users WILL be able to access their desired experience (aloha or Lightning) from EITHER a mobile browser or the Salesforce mobile app.
What Do I Need to Do?
We highly recommend that you test what your users’ experience will be in a sandbox environment BEFORE it gets auto enabled in your production org. To test, please turn off “Enable Salesforce Mobile Web” as shown in this trailhead.
