Somehow my drop-down for global action in lightning is not working. I have gone through the trailhead link as well as some similar questions on stack this and this. But I think I stuck with some salesforce bug. Becasuse when I toggle the device toolbar in my chrome with mobile resolution. its showing those global action see the below picture. but when I open the same layout in desktop mode the global action button is not showing any drop down see the below.
not even standard actions.
I got my head into this issue from last 6-7 hours but I am not able to figure out what is the issue and how to resolve this. FYI I have also check the permission for the global action those are also available. as mentioned here The same issue persists for the quick action also. I have check the record type assignment and permission. If anybody has any doubt about the record type assignment, I have access to these actions in Salesforce1 app on the same browser.
