Safebtc no longer on Uniswap

Question. I own some Safebtc tokens in ERC20. I just noticed that it is no longer listed on Uniswap, which was the only exchange with a trading pair (safebtc / weth). The other exchanges all list pairs for BNB, which are Pancakeswap and IndoEx. I can't use Binance Bridge to swap Safebtc from ERC20 to BEP20 because the coin isn't listed on the bridge. Does anyone know if Ethereum has done an upgrade on this token, and that's why it is no longer listed on Uniswap, or if there is a way I can swap the ERC 20 version for the BEP20 version?
