that is because you have two versions of shareit installed. First, uninstall the pc application. Second, there might be an application installed using the Microsoft store. Make your pc free of all the instances of the application. Again install, and make sure you open it with the same shortcut that got created.
Shareit wants to expand to other countries in future, but for the current website in Finland they require Finnish bank identification to book cars through the website. That kills my idea of suggesting the Tesla for a road trip up north. However I had to ask them if it would be somehow possible for foreigners to rent their Tesla if someone wanted to tour in Lapland and perhaps even over to Norway. It can be arranged. If you are interested to drive one you can visit their website www.shareitbloxcar.fi and contact them directly.
