Can´t find my coins on metamask

I created a binance smart chain folder in my metamsk wallet. I successfully transferred AmmoCoin coins from a swap on pancake swap. When I did a swap for AMMOCOIN on pancakeswap, the coins do not show up in my wallet. I added the REEF token to my wallet, but the balance reads “0”. The transaction seems successful on etherscan.
Any ideas on a solution is appreciated.
