How does application development work and how does development affect the cost of the application? What does it depend on? I want to develop my own application and I don't know if I have enough budget. Is there any way to calculate the cost of developing an application in advance?

Hi everyone,
The Salesforce Gmail integration is no more working with the clients:hasEventContext interface when using aura component, since this week it doesn't fill the start and end field anymore on the dates object.
Does anyone experience the same issue and find a solution ?
The standard Log event is still working and event are created with dates.
Regards,
Pierre
