Apps Documentation

(try! (as-contract (contract-call? .timelocked-wallet claim)))

Does not work on console and gives the error:

Analysis error: use of unresolved contract ‘ST1PQHQKV0RJXZFY1DGX8MNSNYVE3VGZJSRTPGZGM.timelocked-wallet’

I am facing the same issue. Using Safari Windows browser. Is that an issue?
