I bought a Mavic 2 PRO from you in June 2020. Now I have read in an EU regulation that from 2020, among other things, all drones must also have the class identification marks C0 - C4 in addition to the CE mark. These marks are not registered on my drone. Since this marking is obligatory, I will get problems in the event of an inspection, possibly a ban on continuing to fly this model. When you take the EU drone licence, this regulation is mentioned in the documents. Are you actually aware of this? Greetings Gerhard
