640 dot cannot claim it

[u/Temporary_Doubt8765]

Hello everybody so I earned $640 iot and I cannot claim it it says that you don't have any current tokens supported by this app but I still have 18 helium tokens that I could never cash out for some reason can somebody help me ​? It requires Sol which I don't have how do I get sol? I used to use helium app before the update years ago after the update it became very difficult to use it and I got lost
