So I happened to login and book an appointment online and I happened to reach till the end of the process to book an appointment at VFS Mumbai. Firstly there is no option available to select related to passport submission / collection. Second of all no dates are available for this month and for the next month also it says the same thing. Assuming that the online booking must have not been updated since it’s shut. They might update it next month once it reopens hopefully. *Fingers Crossed*
