Help with Schengen visa

I recently got my Schengen visa with a fixed port of entry. However, my travel itinerary within the Schengen zone has changed slightly compared to what I submitted during my application.

I’ll still follow all visa rules (e.g., same port of entry, no overstaying), but I’m concerned if this discrepancy could impact my chances of getting a Schengen visa in the future. Has anyone experienced this? Any advice would be helpful!
