Hello, recently i got my new(old) Ledger nano S. I bought it from one person who bought it early in January, so i had to did the update, which i did, firmware version to 1.4.2 and MCU to 1.5, sucessfully. i was going through instructions on start.ledgerwallet.com. I was updating applications(tokens) and when i came to Ethereum, it says there is not enough space on wallet-that i must delete some tokens to get space.  Can someone explain me how many tokens can i have stored in Ledger, not as many as i wish? did i something wrong when i was installing update? and i didnt yet set a password and nothing because it was said to me first to do the update, maybe something wrong because of this? help please, thanks greetings
