I applied for a Schengen visa for Poland for business travel. I received a multi-entry visa with a validity of 1 year. After receiving my visa, I was requested by my client to cancel my trip to Poland, and was asked to travel to the Czech republic.
Therefore, I will now need to travel to Czechia WITHOUT even visiting Poland. Can I travel with my existing Poland visa? Or should I apply for a new visa with Czechia? I still don't have a clear suggestion if I should apply for a new visa or if I should use my existing visa?
