Hi, Zeroing. Thanks for your attention. Please let me explain one by one.
1) Currently, DJI FLY does not suppot to adjust sensitivity. We apologize for any inconvenience caused. I've transferred your feedback to the product department. Thanks for your advice.
2) Mavic Air 2 does bear CE marking. And it matches the new regulation of EASA. The max transmission distance is 6km under CE standard. Please rest assured to use it in compliance with local regulations. Thank you for your understanding and support.
3) Due to the difference in product supply channels as well as exchange rates and tariffs incurred in different regions, the prices of the products in different regions will vary slightly. You may refer to the price information given on the DJI official website of your current region.
