Your Metamask is set to testnet but not mainnet?
I guess you should check a few details and verify:
Network Name: Smart Chain
New RPC URL: https://bsc-dataseed.binance.org/
ChainID: 56
Symbol: BNB
Block Explorer URL: https://bscscan.com
Let me know if the above details are correctly implemented in your Metamask while adding BSC network in it.
I will try with those settings above now.
