1. I click on the “CONNECT” button, but nothing happens.

You must manually add the proxy:

Choose the type of proxy – MTPROTO

Server: free.mtpro.xyz
Port: 443 or 15
Secret: ddb67bc26648177a20ccd4e20d1b67d980

Also, instead of the word “free” – there can be any word.

WARNING: Don’t use IP address to connect to the server. It can change.

2. I want to donate some money. How will money be spent?

Your money will go to maintain and expand the geography of servers.
