On an Account Object we had created a custom action called 'New Opportunity'.In this action we had defined certain fields and defined predefined values in those field.This was working earlier in Sf1.
Now when I navigate Account Record in Sf1 and in related list of account I click on 'New Opportunity' which is our custom action,as soon as I click on it instead of showing it in Sf1,it launches in mobile browser and display blanks screen. I have checked the page layout & Custom action is added in related list of Account.
Has anyone faced this issued before?
What has changed recently in Salesforce?
