Now there is a web wallet or light version with the ability to import a private key? I don't have the patience to download the whole chain.

No lite or web wallet.
U can download chain here https://blockchain.bitrad.io
In fresh wallet chain downloads very fast.

There is no need to download the Blockchain.

We had a swap 2 Months ago, the Blockchain is new. It takes only a few minutes to sync the wallet.

Yes, it worked, thank you for your support. Transactions until may 28 are not visible? The balance of addresses included in the Genesis block?

all addresses are the same as before.
Transactions until may 28 are not visible anymore because of the chain swap.
