Specially in case of india SMS need the url with cretain headers to be validated and onlky the URL with the header are supported to send out as link .
example if india dlt approved a link like https://abc.com/abcd/<<slug>> but when i use bulk upload approach I am getting the putput links like https://abc.com/<<slug>> this is major blocker for India market and I will suggest this to be resolved on priority .
