I have received a multiple-entry Schengen visa from the Spanish consulate in Mumbai for a meeting that was originally scheduled for the 9th of January, but now has been moved to the 23rd of January. The visa has a validity of 45 days, so it will be valid for my entire stay.
Since I've had to both re-book my flight tickets and change my hotel (due to availability issues), should I notify the consulate about these changes? I've heard of people getting their visas annulled or revoked due to similar things, hence my apprehension. Is there any chances that sending the consulate the new itinerary might lead to any issues with future applications or at passport control?
