Unable to fatch sales service and other options in the app launcher

Hi @Rohit .

Since the App Launcher is working but Sales/Service apps are not appearing, I would check the app assignment and visibility settings rather than cloning the profile again. 

1. Check the Profile's Assigned Apps

Go to: 

 Setup → Profiles → [User's Profile] → Assigned Apps

Make sure Sales and Service are assigned/visible for that profile. Salesforce users only see apps they're authorized to access through their profile or permission sets.  

2. Check App Manager

Go to: 

 Setup → App Manager

Find the Sales and Service Lightning Apps and verify that they are enabled/visible and that the required profile is included in the app's user-profile assignment.  

3. Check App Menu

Go to: 

 Setup → App Menu

Find the Sales and Service apps and make sure they say:

Visible in App Launcher

and not:

Hidden in App Launcher.  

4. Check the cloned profile

Since you mentioned that you cloned the profile, compare the cloned profile with the original profile and verify its Assigned Apps and relevant object/tab permissions.

Also remember that app visibility and object/tab access are two different things. A user may be able to see an app but still not see particular tabs such as Accounts, Contacts, Opportunities, or Cases if their object or tab permissions don't allow access. 

So troubleshoot in this order:

Profile/Permission Set → Assigned Apps → App Manager → App Menu → Object & Tab Permissions 

Hope This Helps!!
