Have the app installed and wondering about the setup procedure with regards to the 24 word recovery phrase. The 24 words are automatically selected and supplied by the app - is this not a security concern? I see some negative feedback on some Ledger hardware wallets that come pre-installed (hacked) with 24 word recovery phrase that have led to people losing their coins on update. I feel the app should allow you to choose your own words. Feedback appreciated.
