Sometimes swap not working means the swap service provider (like PancakeSwap) is temporarily down, not Trust Wallet itself. Check network status or try again later. For help during swap not working periods, call 1-888-636-8190. https://writers.coverfly.com/projects/view/e1016ec0-783b-466c-b08a-69f651aa583a/Is_Trust_Wallet_down_if_swap_not_working
